At present, developed countries require products to meet the EU ROHS environmental protection requirements. Electronic and electrical products that use or contain four heavy metals such as cadmium, lead, mercury, hexavalent chromium, and polybrominated biphenyls and polybrominated diphenyl ethers as flame retardants will not be allowed to enter the EU. In the market, the packaging of positive and negative pressure blister machines is no exception as a packaging accessory for electronic products. PET, PS, and PP materials themselves do not contain these six toxic ingredients, but film manufacturers still have to regularly inspect and require their raw materials to supply. Suppliers provide environmental testing data.
PVC materials usually have lead exceeding the standard, but PVC sheet manufacturers can control the process to make the lead content of PVC meet the ROHS requirements. This is the environmentally friendly PVC that appears on the market, and the price is slightly more expensive.
The raw materials of positive and negative pressure blister machine products are very simple, only film, as long as the film that has undergone rigorous testing is used, the possibility of positive and negative pressure blister machine products failing to meet the standard is very small, but for safety, it is also strictly controlled. The environmental quality of some auxiliary materials such as mold release agent, etc., the positive and negative pressure blister machine products will be inspected periodically to ensure stability.
