The simplest explanation is that they consist of two or more materials bonded together with glue. They are primarily suitable for packaging all kinds of products.
Common composite packaging bag types include paper/plastic, plastic/plastic, and aluminum/plastic. Composite substrates can have two, three, four, five, or even more layers. Depending on the type and thickness of the composite plastic film substrate, the number and order of layers, and the lamination method, a wide variety of composite packaging bags can be created.
1. High Strength: Due to their multi-layered construction, composite bags offer strong puncture and tear resistance.
2. They offer excellent moisture, air, and UV resistance, as well as heat and cold resistance.
3. Aesthetically pleasing appearance: They further enhance the product's value.
4. They offer excellent airtightness and heat sealing properties.
5. Composite bags are chemically stable, resistant to acids and alkalis, can be stored for long periods, are tear-resistant, offer excellent packaging performance, and can accommodate items of any shape or state, including solids and liquids. 6. Composite bags have low processing costs and require minimal technical expertise, allowing for mass production. Furthermore, they are easy to form and made from abundant and inexpensive raw materials.
7. Composite bags offer high transparency, creating a high-end and elegant appearance, and they also provide excellent insulation.
8. Composite bags are strong, perform well, and offer strong impact resistance.
9. Composite bags are lightweight and easy to carry and transport.
Composite packaging bags are primarily used for packaging products such as apparel, hardware, food, medical products, cosmetics, and beverages. In recent years, global demand for composite packaging bags has continued to grow rapidly.
Jiangsu Chuangyou Biotechnology Company has different types of composite bag products. We use three-side sealed cigarette bags, four-side sealed cigarette bags, and eight-side sealed cigarette bags as examples to provide a comparison of their product parameters, hoping to help you make a choice.
