The bag-feeding packaging machine is mainly composed of a bag-feeding automatic packaging machine and a screw scale. This machine has a wide range of packaging and can pack liquid, powder, granules, and solid materials. It only needs to choose different metering and filling according to different materials. equipment. The bag-feeding packaging machine can quickly replace the packaging bag specifications. The width of the automatic bag-feeding equipment can be easily and quickly adjusted through the adjustment handle; Filling is carried out, and the heat-sealing equipment does not seal, thereby preventing waste of packaging materials and raw materials. Compared with the old version of "Technical Requirements for Environmental Labeling Products Packaging Products" (HJ/T209-2005), the main changes in the new version of the specification include: adjusting the name and scope of application of the specification; adding requirements for raw materials and production processes; adjusting the degradation of degradable products The requirements of the target; deleted the original easy-to-recycle packaging; increased the content of bio-based materials and combustion requirements for non-degradable products; increased the requirements for heavy metals in products; adjusted product labeling and storage requirements.
The specific technical content includes: 5.1 Requirements for raw materials and production process 5.1.1 Do not use thermosetting plastics and foamed plastics as raw materials. 5.1.2 The production process of the product does not use azo dyes. 5.1.3 The production process of the product does not add phthalate plasticizers specified in GB/T21928-2008.
5.1.4 The gravure printing process of the product should meet the requirements of HJ2539. 5.2 Product requirements 5.2.1 The four heavy metals lead, cadmium, mercury, hexavalent chromium and its compounds, polybrominated biphenyls, polybrominated diphenyl ethers, and solvent residues in the product should meet the requirements of GB/T10004. 5.2.2 Degradable plastic packaging should meet the requirements of degradation function in GB/T20197-2006.
5.2.3 The bio-carbon content in non-degradable plastic packaging should be greater than 20%, and the emission of harmful substances in the exhaust gas during combustion should meet the requirements in 5.2.8 of QB/T4012-2010. 5.2.4 The content of vinyl chloride monomer in polyvinyl chloride (PVC) products should meet the requirements of GB9681, and the content of styrene monomer in polystyrene products should meet the requirements of GB9692.
