Characteristic


The Alox Metallized PET film is coated with a transparent aluminum oxide layer on the surface of the BOPET film substrate by physical vapor deposition.

It has good thermal stability, high temperature resistance, high strength and stable chemical properties. Compared with co-extruded film, coated film and common metallized film, transparent AlOx metallized film is more environmental friendly, and has better barrier performance and printing performance.

The Alox coating PET film , which is used to package cooked, sterilized food, has gained wide acceptance among consumers who value the convenience of microwaveable meals and “on-the-go” foods. Cailong's new generation of AlOx-coated film, which has excellent thermal stability and superior mechanical properties, including high-strength and dimensional stability, enabling it to withstand the rigors of the converting process and the intense high heat and pressure of retort sterilization. The film’s strength and resilience contributes to the production of a finished, post-retort pouch that has excellent oxygen- and moisture-barrier durability. Typical value, flat sheet oxygen- and moisture-barrier transmission rates for ≤0.5 cc/m2·day and ≤1.0 g/m2·day , respectively.

It resists pinholing, flex-cracking, and scuffing and abrasion, making it a preferred choice over more delicate aluminum oxide-coated films. In standard laminations, it is reverse-printed to create a colorful, attractive package that can be microwaved. Overall, our Alox coating PET film is an excellent option for gusseted and non-gussetted retort bag laminations.

Properties


1. High barrier environmental protection packaging material with excellent oxygen barrier and moisture barrier function;

2. High transparency, light transmittance ≥ 88%;

3. High Al adhesion, greater than 3.0N/15mm, and it has good printing composite performance;

4. Can be microwave heating, and detected by metal detectors;

5. Excellent processing performance with wide application range, can replace KPET, KBOPP, KBOPA, VMPET, SiOx, BOPA, aluminum foil, EVOH and co-extruded film and other packaging materials;

6. Reach FDA, EU, REACH, RoHS and new national standard 4806.7 and other regulatory requirements.



Applications



Widely used in Packaging barrier for food such as meat, cooked food, biscuits, candy, dried fruit, tea, coffee, chocolate, dehydrated food, seafood, flavors, etc. and electronics, daily chemicals, military products, pharmaceuticals, etc.;

Replace the K (PVDC) coated film to greatly improve the barrier properties of the product and reduce the environmental pollution caused by PVDC. It can be boiled and steaming cooked. It has better visibility and no yellowing;

Replacement of BOPA, EVOH and co-extruded film,. It can greatly reduce the cost, greatly improve the barrier performance of the product, and with better adaptability;

In place of SiOx, it can greatly reduce the cost. It has softer hand feeling, better transparency, better processing performance and better environmental recycling treatment;

Replacing the use of aluminum foil, the composite strength is higher, the cost is lower, it can be see-through, microwave heating, and can be detected by metal;

It can replace the common metallized film, has better barrier property and higher composite strength. It can be seen through perspective, can be heated by microwave, and can be detected by metal.

Cautions


1. AlOx is a very thin and transparent dense coating. The processing should make sure that the coating is not scratched and ensure the barrier of the film.

2. Printing and composite refer to metallized film printing composite process. The production process prevents the tension from being too large or unstable, causing the coating to crack and the barrier property is affected.

3. When the customer uses it, it needs to be adjusted according to the equipment and process characteristics of your company. It can be mass-produced only after the product finally meets its own quality requirements.

The above information is only for the use of the customer. Due to the processing conditions of the manufacturer, equipment and final product requirements are different.

Therefore, we are only responsible for the performance of the film, not for each of your specific methods of use and application.

If there is new knowledge and experience in the materials, we will correct the information and will not notify you one by one.
