Poly Bag

The function of a poly bag used on packaging is to provide a lightweight and flexible way to protect and store products. Poly bags are made from a type of plastic called polyethylene, which is durable, water-resistant, and tear-resistant. Poly bags are commonly used in packaging for a wide variety of products, including food items, clothing, electronics, and other consumer goods. They can be customized to fit the specific size and shape of the product, providing a snug and secure fit. Additionally, poly bags can be sealed with a variety of closures, such as ziplock or heat-sealed closures, to ensure that the contents remain fresh and protected during storage or transport.

When used to pack a packaging box, poly bags can serve several functions. Firstly, they can provide an additional layer of protection for the contents of the box, helping to prevent damage or contamination during storage or transport. This is especially important for products that are fragile or susceptible to damage, such as electronics or glassware. Secondly, poly bags can help to keep the contents of the box organized and secure, preventing them from shifting or moving around during transit. This can be especially important for products that are packed tightly together, such as small parts or components. Lastly, poly bags can help to keep the contents of the box clean and dust-free, ensuring that they arrive at their destination in pristine condition. Poly bags can be a useful and effective tool for enhancing the protection, organization, and cleanliness of packaging boxes during storage and transport.
