Lu: su composite membrane paper will meet what kind of production problems?

lu: su composite membrane is widely used in pharmaceuticals packaging paper, as a kind of medicinal outside packaging film, not only than the traditional drug packaging materials is more suitable for carrying, use daily, a general ordinary lu: su composite film also has the very high application advantages, can better protect drug.

lu: su composite membrane in paper printing, composite process, packaging manufacturers often plagued by what kind of production problems? Today, is to simply look at a common quality problems when production - — Paper aluminium heat sealing off layer, this also is substandard a composite strength embodiment.

when packaging manufacturer production, paper and aluminum layer delaminating phenomenon also has a variety of forms, the causes are also different. Lead to paper aluminium heat sealing layer delaminating phenomenon of different parts. One of delaminating phenomenon only appear in heat sealing parts, the intensity of heat sealing parts is good. Largely because of the quantity of heat of heat sealing knife made of adhesive fastness degradation, are heat resistance of the adhesive is not enough or crosslinking curing caused by inadequate.

hot sealing parts of the second paper aluminum-plastic composite membrane and the heat sealing parts of the composite strength is poorer, may be because the paper absorbent strong, leaving coated in oil paper and aluminum foil layer on the surface of the glue water had lead to less, at this time may be appropriately increase the coating weight or use aluminum foil coating way, in order to remedy.

a third and a paper lu: su composite film delaminating phenomenon is the performance of paper layer between layers. Via analysis is due to the paper fiber layer between the bond strength is low, and the water content of the paper itself on the strength and cohesion.
