Application characteristics and knowledge of heat shrinkable film

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

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

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

3. Heat shrinkable film is also the protector of building and transportation materials. It is suitable for the packaging of many products and the packaging with pallets, which is convenient for transportation and sales, easy to realize mechanization, saves labor and material resources, and can partially replace carton and wooden box packaging;

4. It is used for various bottled beer and beverage labels, which can reduce the process of removing labels and facilitate recycling;

5. It is used for bottled beer instead of binding rope packaging to prevent bottled beer from hurting people.

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 vocabulary at present, which is used to describe the practice of reducing the weight of packaging by using less materials to produce packaging.

Advantages of PE shrink film: 1. Large shrink range. 2. The ability of collective packaging is good. 3. The longitudinal shrinkage rate is large. The shrinkage rate is generally ≥30%.

Heat shrinkable film Production Principle The stable state of polymer chain tends to curl. When the polymer is heated and melted in a high elastic state, the orientation of the polymer chain is stretched and straightened under the action of external force, and the orientation state of the polymer chain is frozen when it is cooled to the glass transition temperature. When the temperature rises again, the polymer chain tends to be stable and curls, which shows shrinkage macroscopically. From the shrinkage principle, there is no chemical change, so it is called "physical reducibility". Blow-molding PVC heat shrinkable film is made by using the above principle, after two times of inflation and quick cooling.

Heat shrinkable film has puncture resistance and good performance. It wraps the goods stacked on the pallet, making the package more stable and tidy, so it is widely used. Recently, some customers called to know how heat shrinkable film is. At the request of our customers, heat shrinkable film manufacturers will tell you about heat shrinkable film. If you are interested, have a look.

Heat shrinkable film is suitable for packing goods of various shapes, so it increases the attractiveness of products. Moreover, heat shrinkable film can be close to goods, with transparency and beautiful appearance. The main thing is that heat shrinkable film can protect the packaged goods well, so that the packaged goods are sanitary, clean and sealed, dustproof and moisture-proof. Many customers respond that some products packaged in heat shrinkable film are not, but heat shrinkable film, produced by heat shrinkable film manufacturer, can tightly wrap the packaged goods together, and the small parts will not stagger in the packaging. We are a manufacturer in heat shrinkable film. For several years, the heat shrinkable film produced by our company has been widely favored by people. Because the heat shrinkable film produced by heat shrinkable film manufacturer has met the needs of our customers, and the quality is certain, we have gained a lot in the packaging industry.

Food heat shrinkable film can protect food, protect the freshness of food and prevent dust from affecting food sales. Therefore, heat shrinkable film is still very important and indispensable in our daily use. It can not only insure, but also avoid bad smell. So here's a specific introduction to heat shrinkable film's knowledge:

1, food heat shrinkable film can protect food and prolong the shelf life of food, mainly reflected in:

2. Protect the appearance quality of food and generate corresponding economic benefits.

3. Protect the original quality of food and prolong the shelf life of food.

In addition, food heat shrinkable film can facilitate circulation, prevent food from deteriorating and squeezing during transportation, and prevent dust from falling into it. It is an indispensable food packaging tool in our daily life.
