Packaging thin-wall is a thin sheet material used for packaging, encapsulation, and protection of products. It can be used to package various commodities, including food, medicine, cosmetics, electronic products, etc. The following are some common packaging film series:
1. Polyethylene (PE) film series: Polyethylene film has good water resistance, airtightness, and sealability, and is commonly used in fields such as food packaging and disposable products. It can be divided into high-density polyethylene (HDPE) film and low-density polyethylene (LDPE) film.
2. Polypropylene (PP) film series: Polypropylene films have good transparency, rigidity, and high temperature resistance, and are commonly used in fields such as food packaging and paper product envelopes. According to their characteristics, they can be divided into ordinary polypropylene films and biaxially stretched polypropylene films.
3. Polyester (PET) film series: Polyester films have high strength, transparency, and temperature resistance, and are commonly used in fields such as electronic products, drug bottles, and thin film batteries.
4. Polyvinyl chloride (PVC) film series: PVC film has good flexibility and resistance to acid and alkali, and is commonly used for packaging drugs, cosmetics, stationery, etc.
5. Polyvinyl alcohol (PVA) film series: PVA films have excellent transparency and oxygen barrier properties, and are commonly used in fields such as food preservation films and pharmaceutical packaging.
6. Aluminum foil film series: Aluminum foil film has good barrier, moisture-proof, and thermal insulation properties, and is commonly used in fields such as food packaging, drug packaging, and electronic products.
These packaging film series have different characteristics and applicability according to different product requirements and application fields. When selecting packaging films, it is necessary to consider factors such as product properties, preservation requirements, and degradability to ensure the safety and functionality of the packaging.
