Paper can standards mainly include the following aspects:
- Basic standards
The basic standards for paper cans usually follow the national standard GB/T 10440-2008, which is a general provision for paper cans, covering the basic definition, classification, technical requirements, test methods, inspection rules, and marking, packaging, transportation and storage of paper cans. - Food contact paper can standards
For paper cans used for food packaging, more stringent standards need to be followed to ensure the safety and hygiene of food. Among them, GB 4806.8-2022 “National Food Safety Standard Food Contact Paper and Paperboard Materials and Products” is one of the core standards. This standard specifies the raw material requirements, sensory requirements, physical and chemical indicators, microbial limits and other related requirements for food contact paper and paperboard materials and products. In addition, manufacturers of food paper cans also need to have food-grade paper can purification workshops and stereoscopic warehouses, all of which implement 5S management and comply with food packaging QS production license certification and ISO9001:2008 quality management system certification. - Quality requirements for paper cans
Color and brightness: The color of paper cans should be full, bright and realistic, and the brightness should meet the customization requirements to improve the product grade. At the same time, the oiling process used in printed materials can protect the product, achieve the effect of anti-scratch and anti-dirty, and make the product have a higher smoothness and brightness.
Flatness: The surface flatness of the paper can is required to be within ±1mm to ensure the beauty of the paper can.
Sealing performance: For paper cans that need to be sealed, such as food paper cans, they should have good sealing performance to prevent food from getting damp, oxidized or deteriorating.
Compressive strength: Paper cans need to withstand a certain amount of pressure during stacking and transportation, so they should have a certain compressive strength to ensure the integrity of the paper cans and the safety of the contents.
