PVC / PE composite film production process is dry compound. Adhesive preparation: the main agent, curing agent and solvent according to the ratio by adding stainless steel bucket with a mixer to mix evenly, and then added to the coating head in the plastic tank. After the hard PVC sheet is wound, the surface tension is adjusted by the corona treatment machine. After the coating head is coated with the adhesive, the solvent is dried in the hot air drying tunnel. After the PE film is unwound, the surface is adjusted by the corona treatment machine Tension, and coated with adhesive PVC hard film composite after cooling, winding. The composite material roll is aged at 50-60 DEG C for 3-4 days, then is cut into various products by slitter.
PVC / PVDC composite film production process is reverse gravure coating. Adhesive preparation: the main agent, curing agent and solvent according to the ratio by adding stainless steel bucket with a mixer to mix evenly, and then added to the coating head in the plastic tank. PVC emulsion preparation: PVDC emulsion by adding lubricant additives after adding PVDC intermediate tank, with a pump into the PVDC coating head. After the PVC sheet is put into the roll, the surface tension is adjusted by the corona treatment machine. After the coating head is coated with the adhesive, the solvent is dried in the hot air drying tunnel and then coated with PVDC, The drying process will dry the moisture contained in the PVDC, cool it, and then apply PVDC several times to achieve the desired PVDC coating. Coated good roll in the 50-60 ℃ temperature aging 3-4 days, with a slitter cut into a variety of different specifications of the product.
PVC / PE / PVDC composite film production process is more than two of the synthesis process. As the PVC medicinal tablets and PVC series of medicinal composite tablets are direct contact with non-washable drug packaging materials, so the above process must be in the same net conditions with the pharmaceutical production. In 2000, the State Food and Drug Administration issued Decree No. 21, "Regulations for the Production and Management of Packaging Materials in Direct Contact with Drugs", which is clearly stipulated in this regulation. Therefore, both the hardware and software of the pharmaceutical packaging materials manufacturing plant To achieve the GMP requirements, so as to ensure product quality, while the level of quality management process also directly affect the stability of the quality of PVC medicinal tablets, so the pharmaceutical companies to determine the use of package materials before the packaging plant must be a full range of audit and confirm.
