Application of three-layer nylon in the packaging industry
Tri-layer nylon, also known as multilayer polymer film, is one of the most advanced and widely used materials in the packaging industry.
Due to its multilayer structure, which is a combination of various polymer materials such as polyethylene (PE), polypropylene (PP),
and polyethylene terephthalate (PET), this type of nylon offers unique features such as high strength, moisture protection, and printability.
Azin Plast Kimia Company, one of the pioneers in the production of tri-layer nylon in Iran, and especially in the city of Mashhad,
plays an important role in meeting the needs of the packaging industry by utilizing advanced technologies and providing high-
quality roll label printing services.This comprehensive article examines the applications of tri-layer nylon in the packaging industry,
its types, benefits, manufacturing process, innovations, and environmental impacts, and shows how Azin Plast helps improve
packaging processes.
What is tri-layer nylon?
Tri-layer nylon is a type of polymer film that is composed of three layers of plastic materials with different properties.
Each layer performs specific functions such as mechanical strength, insulation, or printability.
For example, the inner layer may be made of light polyethylene (LDPE) for flexibility, the middle layer of high-density polyethylene
(HDPE) for strength, and the outer layer of polypropylene (PP) for printability and moisture resistance.This multilayer structure
makes the three-layer nylon resistant to oxygen, moisture, and light penetration, making it ideal for packaging sensitive products
such as food, pharmaceutical, and industrial products.
Using advanced machinery imported from Taiwan, Azin Plast Kimia produces high-quality three-layer nylons in various thicknesses
that are suitable for various packaging applications
History and Evolution of Tri-Layer Nylon
Multi-layer nylons were introduced in the 1970s with the advancement of extrusion and lamination technologies.
Initially, these materials were used to package long-lasting food products such as canned goods and frozen products.
With the development of polymer technologies and lamination adhesives, tri-layer nylons have become one of the most widely used materials in various industries.
Today, these nylons are used in the packaging of a variety of products, from food to medical and industrial equipment.
Since 1998, Azin Plast has been producing tri-layer nylons with global standards and supplying them to domestic and international markets, focusing on quality and innovation.Importance of tri-layer nylon in the packaging industry
Tri-layer nylon has become one of the most important materials in the packaging industry due to the following features:
Excellent protection: The multilayer structure of this nylon protects products from moisture, oxygen, light, and microbes.

Recyclability: Some types of tri-layer nylon are recyclable, helping to reduce environmental impact.High durability: These nylons
increase the shelf life of products and reduce waste.
By producing three-layer nylons with customized features, Azin Plast Kimia allows manufacturers to design safe, attractive, and
tailored packaging to their needs.
Types of three-layer nylon in the packaging industry
Three-layer nylon in the packaging industry is divided into different types, each with its own specific applications:
1. Transparent three-layer nylon
Transparent nylon is used for products that need to display the internal contents of the package, such as dry foods (nuts, legumes) or health products.
These nylons allow the product to be viewed without opening the package.
Azin Plast produces transparent three-layer nylons with high strength and excellent printability.
2.Metallized Nylon 3-Layer
Metallized nylons have a metal layer (usually aluminum) that increases resistance to light and oxygen.
This type of nylon is suitable for packaging products such as chips, coffee, and spices. Azin Plast Kimia offers high-quality metallized nylons for these applications.
3. Printed Nylon 3-Layer
This type of nylon allows for printing logos, product information, or promotional designs.
Printing on three-layer nylon helps with branding and attracting customer attention.
By providing high-quality roll label printing services in Mashhad, Azin Plast helps manufacturers provide attractive and professional packaging.
4.Temperature-resistant tri-layer nylon
These nylons are designed for packaging products that require heat processes such as pasteurization or sterilization, such as ready-made foods or canned products.
These nylons are resistant to high temperatures.
5. Biodegradable tri-layer nylon
With increasing attention to environmental issues, biodegradable tri-layer nylons are produced using degradable polymers.
These nylons are suitable for packaging products that require environmental compatibility.
6. Antistatic tri-layer nylon
This type of nylon is used to package sensitive electronic products such as printed circuits or computer components to prevent the
accumulation of electrical charge.Applications of three-layer nylon in various industries
Three-layer nylon has a wide range of applications in the packaging industry.
Here are some of its most important applications in various industries:
1. Three-layer nylon in the food packaging industry
Three-layer nylon is used in the food industry to package products such as dairy products (milk, yogurt, cheese), dried fruits, snacks, frozen products, meat, and ready-made foods.
