This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013

This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013

This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013

This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013

This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013

This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013

This technology ensures maximum product protection, preserving quality, nutritional properties, and safety.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How can the dispersion of chemical substances into the environment be prevented?<\/h3>\n<div>\n<p>In the chemical and agrochemical sectors, to block the migration of chemicals through polyethylene, containers are usually produced in COEX-4, with a nylon (polyamide) barrier layer inserted on the inner layer in contact with the chemical liquid. This reduces the risk of environmental contamination and maintains product integrity.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>What is the composition of COEX-2?<\/h3>\n<div>\n<p>Containers with a COEX-2 configuration usually consist of an outer layer with a soft-touch finish (high cost) and virgin material, allowing the overall material cost to remain low. This type of packaging is particularly widespread in the cosmetics sector, where aesthetics are a decisive factor.<\/p>\n<p>Alternatively, it may consist of virgin material + masterbatch in the outer layer and virgin plastic + regrind or PCR in the inner layer, for packaging that is visually perfect on the outside and more sustainable inside\u2014an ideal solution for lubricants.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-3 containers structured?<\/h3>\n<div>\n<p>COEX-3 bottles are made up of three functional layers: the inner layer in virgin material ensures clean and safe contact with the product, followed by the regrind layer, which enhances production waste and may include black masterbatch for light protection\u2014ideal for photosensitive foods. Finally, the thicker outer layer ensures a uniform and attractive appearance, covering and harmonizing the colors of the underlying layers for optimal packaging presentation.<\/p>\n<p>COEX-3 = Inner \u2013 Regrind \u2013 Outer<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-4 containers composed?<\/h3>\n<div>\n<p>COEX-4 containers consist of four layers with different functions.<br \/>The inner layer is a nylon (polyamide) barrier, directly in contact with the chemical liquid, preventing migration through polyethylene.<\/p>\n<p>This is followed by an adhesive layer, a central layer containing regrind from sprues, and finally an outer layer made of virgin polyethylene (PE) and white masterbatch to ensure a uniform aesthetic appearance.<\/p>\n<\/div>\n<\/li>\n<li>\n<h3>How are COEX-6 bottles composed?<\/h3>\n<div>\n<p>A COEX-6 bottle consists of six distinct layers: the inner layer in virgin material ensures clean contact with the product, followed by a regrind layer that enhances production waste and may provide light protection. A thin adhesive layer allows EVOH to bond with the main polymer, while the EVOH barrier layer protects the contents from oxygen, ensuring optimal preservation. Finally, the thicker outer layer enhances aesthetics and covers the underlying layers.<\/p>\n<p>COEX-6 = Inner \u2013 Regrind \u2013 Adhesive \u2013 EVOH \u2013 Adhesive \u2013
