Comparison of the packaging characteristics of the four pillar packaging materials? And their respective applications and development direction?

1, paper raw materials from rich sources, cheaper, lighter weight paper containers, can be folded, a certain degree of rigidity and compressive strength, good elasticity, a certain cushioning effect. Packaging adaptability, focusing on all over the famous tea brand packaging tin can production customization.

2, plastic light weight, transparent, good strength and toughness, strong, good barrier, water and oil resistance, excellent chemical stability, good molding and processing, easy to heat sealing and compounding. Most of them are suitable for beverage bottles, and are expected to be degradable into plastic products industry development direction.

3, metal mechanical properties, high strength, good rigidity, its containers can be thin-walled and large-scale, and is suitable for large heavy goods and dangerous goods packaging, excellent barrier properties, long shelf life, good molding performance. Can net filling productivity is high, printing and decorating beautiful.

4, excellent barrier properties, can be added to the color material to improve shading; 2. excellent chemical stability, does not contaminate the contents, long-term storage of food, beverages, flavor unchanged, glossy and transparent, beautiful shape, can be recycled and reused. Applicable occasions for liquor bottles, daily packaging glass bottles, canning bottles, medicine bottles and chemical reagent bottles.
