How to extend the shelf life of fresh food by improving the oxygen barrier performance of high barrier films?

In the field of new food packaging, improving the oxygen barrier performance of high-barrier films is a key measure to extend the shelf life of fresh food. Here’s how to achieve this by improving oxygen barrier properties:

Application of multi-layer co-extrusion technology
The oxygen barrier performance of high barrier films can be significantly improved through multi-layer co-extrusion technology. Changxi Packaging Technology (Yixing) Co., Ltd uses advanced multi-layer co-extrusion blown film production technology, combines the characteristics of different materials, and optimizes the film layer structure to improve the oxygen barrier capability of the film. This technology can effectively isolate oxygen in the air and reduce the contact between fresh food and oxygen, thereby delaying the oxidation process and extending the shelf life.

Use high barrier materials
One of the core properties of high-barrier films is their ability to isolate oxygen and other gases. By selecting materials with higher oxygen barrier properties (such as nylon (PA) and high-density polyethylene (HDPE), etc.), Changxi Packaging Technology (Yixing) Co., Ltd. is able to produce packaging films that meet the needs of different fresh foods. These materials can effectively prevent oxygen penetration, reduce oxidation reactions and food spoilage, and improve the preservation effect of food.

Precise control of film thickness and number of layers
By precisely controlling the thickness and number of layers of the film, the oxygen barrier performance of the high-barrier film can be further optimized. Changxi Packaging Technology (Yixing) Co., Ltd customizes the packaging film thickness and layer configuration suitable for different fresh foods according to the individual needs of customers. Thicker films or structures with more layers can provide higher barrier effects and are especially suitable for foods that are prone to oxidation such as cut fruits, vegetables and seafood.

Adaptable sealing performance
High barrier films not only need to have excellent oxygen barrier properties, but also need to have good heat sealing properties to ensure that the packaging is airtight. Changxi Packaging Technology (Yixing) Co., Ltd's high-barrier film can form a seal during the packaging process while maintaining good oxygen barrier effects, completely isolating food from the outside air and further extending the shelf life of fresh food.

Innovative materials and environmental considerations
With the advancement of environmental protection trends, Changxi Packaging Technology (Yixing) Co., Ltd continues to innovate and use materials that meet environmental protection standards to produce high-barrier films. By using recyclable or biodegradable high-barrier films, it can not only improve oxygen barrier performance but also reduce environmental impact, meeting the market's demand for green packaging. These environmentally friendly high-barrier films not only effectively protect food, but also help companies fulfill social responsibilities while meeting food safety requirements.
