polyprop bags

Plastic bags are a common type of packaging material in our daily lives, widely used for various occasions and purposes. Different types of plastic bag materials have different characteristics and uses. Let's introduce several common types of plastic bag materials and their main application areas.   Polyethylene (PE) bags : Polyethylene bags are the most common type of plastic bags, characterized by high transparency, flexibility, and tear resistance. They are widely used in food packaging, shopping bags, garbage bags, etc. Due to the recyclability and good chemical stability of polyethylene materials, it remains a popular choice in today's increasingly environmentally conscious society.   Polypropylene (PP) bags : Polypropylene bags have high strength and durability, commonly used for packaging heavy items, frozen foods, bread, pastries, etc. Their advantages include water resistance and chemical corrosion resistance. Furthermore, they are easier to recycle and reuse compared to polyethylene bags.   Polyvinyl chloride (PVC) bags: Polyvinyl chloride bags have good transparency and flexibility, commonly used for packaging cosmetics, pharmaceuticals, stationery, and other products. However, caution should be taken when using them as they contain environmental pollutants such as chlorine gas, and it is important to avoid high temperatures and long-term exposure.   Biodegradable plastic bags: To reduce environmental impact, biodegradable plastic bags have emerged. These bags are typically made from materials such as plant starch, biopolymers, etc., and they have high biodegradability. They can decompose under appropriate environmental conditions, reducing the burden on the environment.
