Precautions for stretch film

一、Categories and uses of stretch film

Stretch film is a type of packaging material and is a film made of polyethylene. Stretch film has the advantages of high stretchability, acid and alkali resistance, water and moisture resistance, etc. It is widely used in industry and commerce, especially playing a key role in logistics and transportation.

In industry, stretch film is mainly used to package heavy products such as large machinery and equipment, wood, and building materials. It can protect items from damage and prevent the intrusion of moisture and dust. In business, stretch film is used to preserve freshness, prevent food from spoiling, and protect household items and other fragile items.

二、How to use stretch film

1. Preparation work:Place the items to be packed on a flat surface, tear off a section of the stretch film in advance, and place it on the items to facilitate packaging.

2. Start packaging:Fix one end of the stretch film on the item, then gradually stretch and fix it on the other end. Repeat the above steps several times until the entire item is completely covered.

3. Determine the strength:Pay attention to the strength of the stretch film during the packaging process. If the stretch film is not strong enough, the stretch film will not protect the items securely. If the force of stretching the film is too large, it may cause the item to deform and affect the use effect.

4. Fix the edge:After packaging is completed, the edge of the stretch film must be fixed on the surface of the item to ensure that the stretch film will not slide or fall.

5. Cutting and finishing:Cut the stretch film with scissors and finish.

三、Things to note when using stretch film

1. Select the appropriate stretch film according to the size of the items being packaged to ensure that they are tightly wrapped and protect the items to the greatest extent.

2. Use stretch film in a dry and clean environment to avoid interference from moisture and dust.

3. Try to avoid putting heavy pressure on the stretch film, otherwise it will easily tear.

4. Make sure the surface of the goods is clean and dry before packaging, otherwise the wet or water-stained surface will affect the effect of the stretch film.

5. When packaging, the stretch film should be evenly covered on the entire surface of the goods to avoid varying degrees of aging, UV weakening, relaxation, etc., which will affect the goods.

6. The stretching of the stretch film should be moderate. Excessive stretching will cause damage and affect the packaging effect.

7. Pay attention to the cutting tools used. High-speed steel saw blades should be used for saw cutting.

8. Before cutting the stretch film, a pressure test should be conducted on it, including a pressure test on the membrane product and a pressure test on the membrane channel system, to check the pressure strength and tightness of the membrane product itself.

9. Pay attention to the ambient temperature and storage conditions to avoid over-stretching and use stretch film safely and effectively. During storage, it should be placed in a dry, well-ventilated place, away from direct sunlight and high temperature environments.

Following these precautions will ensure you get better packaging results and extend its life when using stretch film.
