What are the different types of plastic packaging? And what are some everyday uses?

　　Plastic packaging is a common type of packaging used for most goods we encounter in daily life. I'm sure you're familiar with it. In this article, I'd like to discuss the specific classifications of plastic packaging and how different classifications are used in various aspects of life. Which type of plastic packaging is right for your product? After reading this article, you'll be able to make a choice. 
　　How are common plastic packaging types currently classified in the market? A simple way to distinguish them is as follows: 
　　First, if classified according to the packaging function required by the product, it can be divided into three-layer composite packaging bags and special packaging bags. The three-layer composite packaging bags are generally BOPP/PET/PE, BOPP/WMPET/PE, and BOPP/PE, and can be used for most packaging, such as dried fruit packaging bags, seasoning packaging bags, candy packaging bags, vacuum-packed roast duck packaging bags, and many other products. This type of packaging material can be used for most products. 
　　Special packaging bags are further divided into the following types: ① For rice packaging bags, millet packaging bags, seed packaging bags, and pet mixed grain packaging bags, if they exceed 2kg, it is recommended to use BOPA/PE or PET/BOPA/PE. BOPA has strong tensile strength, high oxygen barrier properties, and a soft texture. ② High-temperature sterilization packaging bags: including braised egg packaging bags, roast duck inner packaging bags, and other cooked food inner packaging bags, mostly using BOPA/RCPP, because both BOPA and RCPP are heat-resistant, and there are no problems at 121 degrees for 30 minutes and 131 degrees for 30 minutes. 
　　③ Chemical product packaging bags: including pesticide packaging bags and corrosive chemical product packaging bags, mostly using PET/BOPA/AL/CPP. However, because it uses corrosion-resistant adhesive composite, and CPP still has a certain degree of air permeability, if used for a long time, if the corrosive liquid contacts the corrosion-resistant adhesive through CPP, it may cause delamination. 
　　④ Cleaning products: laundry powder packaging bags and laundry detergent stand-up pouch spout bags. Laundry powder packaging bags mainly use BOPP/milky white PE. 
　　If classified by bag shape, the packaging bags currently used in the market are also divided into many types according to different needs, such as stand-up pouches, stand-up zipper bags, three-side seal zipper bags, stand-up spout pouches, shaped bags, ordinary three-side seals, back-seal pillow bags, five-side seals, center-seal bags, etc. Each has its own characteristics and can better protect the goods. 
　　There are many considerations in choosing plastic packaging. It is best to "customize" it according to your product's needs to achieve better results, enhancing the product's visual appeal and providing more comprehensive protection to prevent losses. You can leave your requirements, and we will recommend suitable packaging types!
