The PA / PE five layer coextrusion nylon film is a kind of high barrier film with excellent performance, which is made of various single materials (PA, PE) through multi-layer co extrusion equipment. It has the following advantages:
Improve the quality of films and give them special properties
Five layer co extruded nylon film has the gas barrier property of nylon film and the water vapor barrier property of PE film. It has good heat sealing property, high mechanical property, puncture resistance and low temperature resistance.
Improvement of post processing properties of films
It has strong adaptability to heat sealing bag making and automatic packaging.
Environmental protection, non-toxic
The traditional dry composite production of high barrier film needs adhesives and solvents, which pollutes people and the atmosphere. However, this situation does not exist in the high barrier film produced by CO extrusion.
Product composition
The basic structure of the five layer coextrusion nylon film is PE / adhesive layer / PA / adhesive layer / PE. Due to the addition of nylon (PA), the barrier to oxygen, carbon dioxide, water vapor and odor is greatly improved, so as to keep the product fresh and keep quality.
Product features
1. Low oxygen permeability (high barrier): the barrier properties of different plastic materials are quite different. Coextrusion film can co extrude various kinds of plastics with different functions into a film to achieve high barrier effect on oxygen, water, carbon dioxide and odor.
2. High strength and puncture resistance: nylon, metallocene plastic resin and other plastic materials are added in the middle of the coextrusion film to make it have the composite strength higher than the general plastic packaging, without delamination phenomenon, good flexibility and high heat sealing strength.
Strong function: oil resistance, moisture resistance, high temperature cooking, low temperature freezing resistance, preservation, odor preservation.
Small volume ratio: the coextrusion film can be packed by vacuum shrinkage, and the volume ratio is nearly 100%, which is incomparable with glass, tin can and paper packaging.
No pollution: no adhesive, no residual solvent pollution, green environmental protection.
Product use
1. Vacuum deoxidation bag (five layer co extrusion nylon bag) is widely used in the packaging of food, raw and cooked meat products, dairy products, bean products, aquatic products, marine products and other products. It can maintain the special flavor, prevent oil oxidation, prevent oil penetration, and keep the outer package clean. It is also used in aseptic packaging and modified atmosphere packaging. It can endure 100 ℃ water boiling and high temperature cooking 121 ℃ for 30 minutes. And used to make a variety of barrier film substrate.
2. It can prevent aflatoxin pollution and mildew of grains and products, such as rice, peanuts, sesame, beans, walnuts, grains, feed, tobacco and other small packaging circulation sales. It can prevent insect moth, caking and deterioration, and prolong the shelf life.
3. It is used for packing all kinds of vegetables, fruits and flowers.
4. It is used for moistureproof, anti oxidation, yellowing and deterioration of various precious Chinese herbal medicines.
5. For tea, coffee, cocoa, spices, oils, cosmetics to maintain fragrance, color.
It is used for anti-oxidation and corrosion packaging of industrial machinery parts, electronic industry components and precision machinery, optical components, military machinery, etc.
