There are many types of carton series for Lingxian packaging. According to different production processes and different materials, carton packaging can be divided into many types. Different types of items suitable for storage are also different, so we must understand what classification it has before using it? Today, Lingxian Packaging will introduce the various classifications of Lingxian cartons.
1. Classified by paper materials packed in cartons
Paper quality can be divided into corrugated boxes, single-layer cartons and so on. Generally, the number of layers of cardboard can be divided into three and five layers, and seven layers are less used. The different layers of the carton can be divided into: liner paper, corrugated paper, kraft paper, facial paper, etc. These materials are different, so I just want the touch and thickness to be different. When we choose carton packaging, we usually prefer to choose a carton with a smoother surface. This paper is more suitable for waterproofing and has better hardness.
According to the weight per unit area, it can be divided into paper with a weight of (250g / M * M), paper with a weight of (175g / M * M), and paper with a weight of (125g / M * M). The above three are generally imported paper. The paper is hard and thick. It is suitable for storing more expensive items such as household appliances and large car parts. Among them, K paper has the best quality, A paper is second, and B paper is slightly inferior, but they are all relatively good paper materials. The more common household papers are 140g / M * M, 150g / M * M, 180g / M * M enhanced core paper.
Three, according to the cardboard structure of the carton packaging
Generally, the cross section of the cardboard has holes or gaps, and it is not a simple storage cardboard. According to its different holes, the carton structure can be classified. The common ones are Wave A, Wave B, Wave C, Wave D and Wave E. In our country, waves B, C and E are more suitable. The height of wave A is 5mm, the height of wave B is 3mm, the height of wave C is 4mm, the height of wave D is 2mm, and the height of wave E is 1.5mm. The higher the wave height, the better the carrying capacity and compressive capacity. The five-layer cartons commonly used in our lives usually choose BC two types of ingredients.
