Shrink bags are a type of plastic packaging used to wrap and protect items. They are made of a plastic film that has the ability to shrink, similar to shrink film. They can be used for the packaging of various items and provide protection by creating a barrier against air, dust, and weathering. They can package almost anything that fits inside.

What are the benefits of using shrink bags?

Firstly, they provide protection by tightly sealing the items inside the shrink packaging. They create a complete barrier against the outside air and protect the contents from dust and degradation. They can also extend the shelf life of perishable items such as fruits, vegetables, and meats.

Generally, for a shrink packaging to be durable and sturdy, it requires the use of robust materials such as PVC or POF. POF is a safer option and widely used in food packaging, both in the food industry and retail sector. However, in warehouses and factories, polyethylene film is more commonly used.

Shrink bags can also serve as tamper-evident packaging. Important documents, food and pharmaceutical companies, banks, and government institutions often utilize shrink packaging to prevent tampering. When someone intentionally tries to modify the sealed item, the plastic will change color during the stretching process, indicating that the seal has been tampered with.

POF shrink bags are extensively used in the food industry to extend the shelf life of food products. Food-grade polyolefin shrink packaging is a standard choice for food production companies.
