Paper packaging products account for over one-third of the packaging industry due to their recognized hygiene, safety, environmental friendliness, and recyclability. With the increasing emphasis on food, medicine, and hazardous chemical safety, as well as the improvement of environmental protection awareness, the requirements for packaging and transportation safety of such goods are also becoming higher and higher. This type of product packaging must have the following performance: 1) safety protection performance for the quality of the contents, which involves shielding, protection, stability, and hygiene safety; 2) Mechanical processing performance, involving processability, printability, heat sealing, etc; 3) Easy to use performance, lightweight, easy to carry, storage, opening, and easy to purchase with clear markings; 4) Economic performance refers to the simplicity, rationality, and energy efficiency of production; 5) Environmental performance refers to both recyclability and degradability. According to the above requirements, among various existing packaging materials, the industry generally favors all paper packaging. Paper itself has moisture absorption properties, which can absorb excess moisture in the contents and effectively prevent the contents from getting damp due to humid environments. The outstanding advantages of all paper drums are non-toxic, odorless, pollution-free, good shielding, strong rigidity, and no chemical reaction with various fine chemical products. They will not cause explosive products to explode or catch fire due to friction, nor will they cause non combustible materials full paper bucket or paperboard drum The locking clamp is corroded. Due to the good printing performance of paper materials, graphics and text can be printed according to user requirements, which facilitates product promotion and sales. Full paper packaging drums have been widely used in the packaging of fine chemicals such as chemical raw materials, food additives, pharmaceutical intermediates, pigments, etc. It can be said that full paper drums have become the preferred packaging for pharmaceutical, light industry, chemical, pharmaceutical production plants, and foreign trade companies to contain domestic and export products and dangerous goods.

Based on years of industry experience, Danqi,full paper bucket The quality requirements for production quality standards are as follows:

For paper drums used for export product packaging, the quality should meet the requirements of SN/T0270-93 "Inspection Regulations for Export Commodity Transport Packaging Cardboard Drums", and the appearance should meet the following requirements:

1. The paper bucket should be round and free from obvious defects such as roundness, concavity, skewness, deformation, etc.

2. The barrel body is smooth without mechanical damage, wrinkles, or glue peeling. The waterproof paint is evenly applied without any omissions, bubbles, or obvious sagging.

3. Round rolled edges with smooth and paperless tongue.

4. The barrel hoop should be welded firmly and smoothly, without burning through or virtual welding, and without obvious rust, peeling, or cracking.

5. The closure is firmly connected and can be opened flexibly. After closure, the lid and bottom of the barrel are well sealed.

6. Galvanized or painted barrel clamps and closures should be shiny and free from detachment.

When printing graphics on the barrel, they should be clear, uniform, firmly attached, and free of ink running.

8. The inside and outside of the paper bucket are clean and free of oil stains.
