Heat shrinkable film Packaging and Market Performance

Heat shrinkable film needs to have good puncture resistance, good shrinkage and corresponding shrinkage stress. In the process of shrinkage, the film cannot produce holes. Since the shrink film is often suitable for outdoor use, it is necessary to add UV anti-ultraviolet agent. Includes OPS/PE/PVC/POF/PET shrink film.

Lightweight packaging in heat shrinkable film should become the mainstream trend. Lightweight packaging is beneficial to the environment and the profits of enterprises. Lightweight is a commonly used industrial term at present, which is used to describe the practice of reducing the weight of packaging by using less materials.

Heat shrinkable film film is mainly designed by the principle of stretching orientation of high-retrieval molecular chain. Its physical principle is that when the ionomer is in a high elastic state, it is stretched orientation. When the polymer is quenched below the glass transition temperature, the molecular orientation is frozen. At this time, when the article is packaged, the molecules will return to their original state and shrink due to the relaxation of molecular motion stress. At present, there are PE shrink film, heat shrinkable film, PP shrink film, POF co-extrusion shrink film and so on in heat shrinkable film. In the big family of heat-shrinkable heat shrinkable film, POF three-layer co-extrusion heat shrinkable film is a new generation product that has gradually emerged and been accepted by people in recent years.

Heat shrinkable film needs to have good puncture resistance, good shrinkage and corresponding shrinkage stress. In the process of shrinkage, the film cannot produce holes. Because heat shrinkable film is often used outdoors, it is necessary to add UV-resistant agent.

At present, the application of heat shrinkable film in the domestic market mainly shows the following characteristics:

1, used for bottled beer instead of tying rope packaging, to prevent bottled beer from hurting people;

2. It has been widely used in fast food, ceramic products, tea sets, mechanical parts and other areas;

3. Heat shrinkable film is also the patron saint of building and transportation materials. It is not only suitable for the packaging of multiple products and packaging with pallets, but also convenient for transportation and sales, easy to realize mechanization and save labor and material resources, and can partially replace the packaging of cartons and wooden cases;

4. It is of great significance to apply the combination of heat shrinkable film and gas phase antirust technology to replace antirust oil in hardware tools to enhance antirust ability;

5. It can be used to label various bottled beer and beverages, which can reduce the process of removing labels and facilitate recycling;

Heat shrinkable film is not only used as a shrink label, but also used in the outer packaging of daily commodities. Because it can not only protect the packaged goods from impact, rain-proof, moisture-proof and rust-proof, but also make the products win users with beautifully printed outer packaging, and at the same time, it can well show the good image of the manufacturers. More and more packaging manufacturers use printed shrink film instead of conservative transparent film. Because printing shrink film can improve the appearance grade of products, is conducive to product advertising, and can make trademarks have a deep impression on consumers.

Heat shrinkable film is mainly used for winding packaging of products and goods, which can make the packaged goods more stable and stable. It is also the case that this product has been widely used in various industries, especially in the building materials industry. So, have you considered how to store the unused products?

With the widespread use of heat shrinkable film in daily life, manufacturers should meet the requirements of simplicity, practicality and environmental protection from the beginning of packaging design.

1, the characteristics of heat shrinkable bag

Good transparency, moisture-proof, water-proof, excellent insulation and strong antifouling. Shrink-packed products have the characteristics of compactness, crispness and beauty, and the heat shrinkage temperature is low, so the packaging is simple.

2. Use of heat shrinkable bag

It is suitable for light and small products such as food, drinks, electrical appliances, daily necessities, toys, cosmetics, light industrial hardware, etc. The film used for labels is suitable for product labels and once-opened purposes after printing, and many standard sets after setting are used for packaging wine bottles.
