High barrier shrink film is a material used for packaging, protection and preservation of food.
High barrier shrink film is a material used for packaging, protection and preservation of food. It is highly contractile and has excellent barrier properties, which can effectively extend the shelf life of food, and can provide excellent appearance and packaging results.
High barrier shrink films are composed of a variety of materials, including polyethylene, polypropylene, nylon and PET. These materials have different properties such as softness, ductility and temperature resistance, and the right material can be selected according to the desired application.
The contractility of high barrier shrink films is achieved by introducing heat treatment in the manufacturing process. During the process of heating, the polymer chains in the film contract through the action of heat, so that the entire film shrinks and adheres to the package. This shrinkage property allows the high barrier shrink film to tightly wrap the food, thus effectively protecting the freshness and quality of the food.
In addition to shrinkage properties, high barrier shrink films also have excellent barrier properties. It can effectively block the invasion of external factors such as oxygen, water vapor, odor and bacteria, so as to maintain the freshness and taste of food. This barrier performance can extend the shelf life of food and reduce food loss and waste.
High barrier shrink films also provide excellent appearance and packaging. It can be customized according to the need for different colors, transparency and printing effects, making the packaged food more attractive. This appearance can enhance the market competitiveness of the product and attract the attention of consumers.
In short, high barrier shrink film is a packaging material with high shrinkage and excellent barrier performance. It can effectively protect the freshness and quality of food, and provide excellent appearance and packaging results. In the field of food packaging, high barrier shrink films will play an important role in providing people with safer, more convenient and beautiful food packaging solutions.
