Polyamide/aluminum/polyvinyl chloride cold stamping forming solid pharmaceutical composite hard sheets (abbreviated as PA/AL/PVC, hereinafter abbreviated as cold forming composite hard sheets) among pharmaceutical composite hard sheet products are gradually recognized by more and more pharmaceutical enterprises in China for their excellent packing property and barrier property, and development is extremely rapid, and demand is rising year by year.
The cold-formed composite hard sheet takes the polyamide film as a printing layer, and the polyamide film can also play a role in preventing the aluminum foil from being oxidized and protecting the aluminum foil from being cracked in the process of brewing; the aluminum foil is used as a barrier layer to block water and oxygen; the polyvinyl chloride film is a heat-sealing layer and is heat-sealed with medicinal aluminum foil. The product is generally produced by a dry process composite process, and has the advantages of attractive and smooth appearance, light shielding, oxygen blocking, good moisture blocking performance and the like.
The quality standard of the cold-formed composite hard sheet is the national pharmaceutical pack standard YBB00242002-2015 polyamide/aluminum/polyvinyl chloride cold-stamping formed solid pharmaceutical composite hard sheet. Wherein, the peel strength is as follows: reference peel strength assay (YBB 00102003-2015). The interlayer peel strength of PA and AL is not lower than 8.0N/15 mm; the peel strength between AL and PVC should not be lower than 7.0N/15 mm.
The peel strength of the adhesive is required to be impossible to achieve by common double-component adhesives, and most of domestic cold aluminum manufacturers currently use imported double-component polymers special for DowThe cost of the urethane adhesive AD502S is very high, and the cost is 7-10 ten thousand/ton; the price of the common steaming polyurethane adhesive is 2-4 ten thousand/ton, and the common steaming polyurethane adhesive can only reach the peeling strength of 3-5N/15 mm. Although some adhesive manufacturers develop alternative adhesive products special for cold aluminum in China, the price is obviously higher than that of a common cooking type double-component adhesive by 5-7 ten thousand/ton except that the performance and import are still different. The coating weight of the special adhesive AD502S for import is required to be 5.0-5.5 g/m 2 Can meet the standard requirements.
