Application carton so widely used, has brought us convenience, which has several cartons? What are the carton materials ? This may be a question that everyone often asks. The material of the carton is really more. Today, Xiaobian will briefly talk about the problem of carton and some carton nouns.
Cardboard materials are classified by weight per unit area:
What are the carton materials ? There are mainly the following paper sheets in the mainland market:
K paper: 250g/M*MA paper: 175g/M*MB paper: 125g/M*M (The three types are generally imported paper) 7 paper: 200g/M*M 8 paper: 260g/M*MC paper: 127g /M*M (Taiwan paper)
Core paper: Basic 100g/M*M Large machine 105-110g/M*M Reinforced core paper: + Paper 115g/M*M Other reinforcing cores are subject to customer's condition. In Taiwan, there are 130g, 140g, 150g, 180g 190g/M*M reinforced core paper, but common in the mainland there are 140g, 150g, 180g/M*M reinforced core paper.
Corrugated cardboard is made by bonding paper, backing paper, core paper and corrugated paper processed into corrugated corrugated. According to the requirements of commodity packaging, corrugated cardboard can be processed into single-faced corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer corrugated paperboard.
Corrugated cardboard of different corrugated shapes has different functions as corrugated cardboard. Even with the same quality of face paper and backing paper, the performance of the corrugated board formed is different due to the difference in the shape of the enamel. There are four types of corrugated shapes commonly used in the world, which are A-type C, C-type 楞, B-type E and E-type 楞. Their technical indicators and requirements are shown in Table 1. Corrugated cardboard made of type A enamel has good cushioning property and a certain elasticity, and type C 楞 is second to A. However, the stiffness and impact resistance are better than that of the A-type crucible; the B-type crucible has a high density of arrangement, the surface of the corrugated cardboard produced is flat, and the bearing pressure is high, which is suitable for printing; the E-shaped crucible is thin and dense, and presents its just strength. The difference between container and non-container is mainly in the outer diameter and is closely related to the type of corrugated.
Through the introduction of the above-mentioned carton materials , I believe that you have a lot of knowledge about the carton knowledge, I hope to help you more to understand the knowledge of the box packaging.
