　　Beverages and liquids

　　Beverage, liquid and food packaging is a method of putting beverages (or liquids) into containers with certain specifications, sealing and sterilizing them for storage, transportation and consumption. There are many common liquid beverages on the market. The packaging forms are different according to the characteristics of liquid beverages and product characteristics. The following is an introduction to the five common packaging forms of liquid beverages.

　　1. Paper-aluminum-plastic composite film

　　Sterile bricks: have certain sealing, moisture-proof and waterproof properties, low cost, light weight, easy to carry and transport, but cannot be heated and sterilized.

　　2. Plastic composite film

　　Packaging bags: Commonly used are composite film materials containing high barrier materials such as EVOH and PVDC, which have good barrier properties, low cost, and are easy to transport and carry.

　　3. Plastic containers

　　Plastic bottles: Common plastic bottle materials include HDPE, PP, PET or PETP, etc., which have good mechanical strength and air tightness. Among the above material structures, PET bottles have higher barrier properties.

　　4. Metal containers

　　Metal containers: have excellent barrier properties and light-shielding properties, allowing packaged beverages to have a long shelf life. However, improper transportation may lead to extrusion deformation and poor chemical stability.

　　Aluminum alloy: mostly two-piece cans, mostly used for packaging carbonated drinks.

　　Tinplate: mostly three-piece cans, often used for packaging non-carbonated beverages.

　　5. Glass container

　　Glass bottles: good barrier properties, airtight, heat-resistant, pressure-resistant, and cleaning-resistant. They can be sterilized at high temperatures and stored at low temperatures, but are not easy to transport, are heavy in weight, easily damaged, and have poor printability. Often used to package fruit tea, fruit vinegar, jujube juice and other beverages.
