Corrugated mailing boxes raw materials lining brief, corrugated can produce many types of mailer boxes, if you want high hardness need to improve the quantity of layers of corrugated to improve the hardness standard, usually five layers of corrugated hardness standard can need to pack heavy  goods. Mailer boxes raw material corrugated classification is very particular. Corrugated paper is composed of surface paper, inside paper, core paper and composite corrugated paper according to the bonding. According to the requirements of product packaging, corrugated paper needs to be processed into single and double side corrugated paper, three layers of corrugated paper, five layers, seven layers, eleven layers of corrugated paper. The production and manufacturing dimensions of the mailer boxes connector are determined by the quantity of corrugated layers and the level of production and manufacturing technology. The single corrugated paper is 30 ~ 45 mm, the double corrugated paper is 40 ~ 55 mm, and the three corrugated paper is 60 mm. The raw material of the mailer boxes can be divided into several layers. Usually, the surface area of the mailer boxes is estimated by referring to the commodity. After the aircraft box is expanded, the specific shape size of the mailer boxes is analyzed according to the specific style of the mailer boxes. The length, width and height should be determined according to the accurate measurement. The raw materials of mailer boxes are generally composed of surface paper, inner paper and core paper. Because of the continuous improvement of the concept of environmental protection, "nature", "ecological environmental protection" is more and more concerned by everyone. Therefore, in the social development, there is often a fashionable topic to discuss: green packaging. Raw material biodegradation means that in order not to produce permanent waste, the packaging waste which can not be turned into valuable waste should be corrupted, and the purpose of improving the soil layer can be achieved according to the fertilizer. Pulp molded packaging is a common multipurpose biodegradation packaging.
