Environmental protection wire film brief introduction to green packaging materials

It is conducive to the preservation of fresh products. In addition to the advantages of light weight, low price, and shock resistance, the molded pulp products also have good air permeability. In international commodity circulation, it is widely used in the turnover packaging of eggs, fruits, glass products and other fragile, fragile, and squeezable items.

1. Repeated reuse and regeneration

For beer, beverages, soy sauce, vinegar and other packaging, glass bottles are used repeatedly. Repeat and reuse packaging materials.

There are two ways to regenerate and recycle packaging. The physical method refers to direct complete purification and crushing without any residual pollutants. Dongguan stretch film supplies the processed plastic packaging materials and then directly uses them in recycled packaging containers. The chemical method means that after the recovered PET is crushed and washed, the PET is completely depolymerized into monomers or partially depolymerized under the action of a catalyst, and the monomers are re-polymerized into regeneration after purification.

It only prolongs the service life of polymer materials such as plastics, reuse and regeneration. After reaching its service life, it still faces the problems of waste disposal and environmental pollution.

2, edibility

The glutinous rice paper used on the familiar candy packaging and the corn baking cup for ice cream are all typical edible packaging. Dongguan stretch film supplies edible packaging film. For decades.

It is edible, a naive transparent, colorless, odorless, non-toxic, tough, and highly oil-resistant film among synthetic edible packaging films. Can be used for food packaging. Its gloss, strength, and folding resistance are relatively good.

It has been developed into an edible cling film with a variety of functional properties, obvious waterproofness and a certain optional breathability. As early as the 1213th century, China used wax to coat oranges and lemons to delay dehydration and weight loss. Extend the shelf life of fruits and vegetables. Edible plastic wrap is generally used now. Therefore, it has broad application prospects in the food industry, especially in the preservation of fruits and vegetables.

3. Degradable materials

A plastic whose chemical structure has changed. Degradable plastics have both the functions and characteristics of radical plastics. The supply of degradable materials in Dongguan stretch film refers to the specific environment that causes performance loss in a specific time. After the service life is completed, through the action of ultraviolet light in the sun or the action of microorganisms in the soil and water, the natural environment can be split, degraded and reduced, and finally re-enter the ecological environment in a non-toxic form and return to nature.

4. Paper materials

Nature will decay quickly, and the raw material of paper is mainly natural plant fiber. It will not cause environmental pollution, and it can be recycled and re-made paper. Paper materials are also used for many purposes, such as pulp injection molding parts, composite materials, and construction materials.
