English1. Wide variety and wide application
In flexible packaging plastics, not only can different plastics, different formulas, and various single-layer films with different properties be manufactured through different processes, but also hundreds of different varieties can be obtained through different combinations of multiple materials. Meet a variety of different needs.

2. Different performance, strong adaptability
Due to the wide variety of flexible packaging materials, the performance span is large, and products with similar and similar performance to completely different products are all industrialized. For example, the properties of LDPE film and EVA film are very similar, and both have good transparency, flexibility, low temperature resistance, good air permeability, good hygiene, easy sealing and bag making, etc., but they have poor heat resistance. Common shortcomings, but EVA's flexibility and low temperature resistance are more prominent, and its heat resistance is worse than LDPE. There are also many products with completely different properties, such as polyolefin films with outstanding water and moisture resistance, such as polyethylene, polypropylene films, etc., and polyvinyl alcohol films that are completely dissolved at room temperature; both are produced with stable formulations Anti-aging film, there are also degradable environmental protection films that can be quickly degraded in a short time after use; there are both highly transparent all-plastic flexible packaging materials, and completely opaque (light-proof) aluminum-plastic and paper-plastic composite products ; There are both high-gloss flexible packaging materials and matte varieties; there are both breathable films and barrier varieties. Among barrier varieties, there are high barrier and medium barrier. Taking advantage of the different performance characteristics of different flexible packaging materials, it is possible to meet the packaging needs of many commodities through the reasonable selection of varieties, regardless of the specific needs of commodities such as daily necessities, textile products, photosensitive materials, fresh fruits and vegetables, steamed food, pharmaceuticals, etc. Plastic flexible packaging materials can generally be solved satisfactorily.

3. Low consumption of raw materials and significant data saving
The flexible packaging materials are all film-like objects with a relatively small thickness, generally only about 0.04um, and the mass per square meter is only about 0.025kg. Therefore, the use of flexible packaging materials for commodities can significantly save resource consumption compared with other packaging materials.
