Your paper lu: su composite packaging film still delaminating problems? Come and see!

Everybody is good, small make up and meet you again, you want to me? Today, we sum up the paper lu: su composite packaging film, it is widely used in pharmaceuticals packaging, packaging products is more suitable than traditional drugs not only at ordinary times, take on the belt, and than the average general lu: su composite packaging film also has very high use of advantages, to maintain drug as soon as possible. Lu: su composite packaging film in paper packaging printing, composite processing technology, packaging printing plant in daily work will suffer what manufacturing problem confused? Today, small make up is easy to lead the people know about the manufacturing a product quality problems in the common - — Paper aluminium layer heat sealing off, this is a reflection of the compressive strength of the composite is unqualified. Manufacturer in production and manufacturing, aluminum layer to take off the paper status is also a variety of forms, its cause is different also. Cause paper aluminium layer heat sealing off status of different parts. One: delaminating situation has only appeared in the hot sealing parts, the heat sealing part compressive strength is good. Is probably due to the heat sealing knife calorific value prompted adhesive fastness deterioration, more is the insufficient resistant viscose agent or chemical crosslinking dry solid caused by inadequate. Second: paper lu: su composite packaging film sealing parts and the hot sealing parts of the compressive strength of the composite are weak, will be due to the speed of paper that is strong, slightly lower sizing amount prompted for the paper surface and aluminum platinum layers in the middle of the glue flow caused by too little, then to moderately enhance sizing quantity or by the method of aluminum foil dispensing, save for it. Thirdly there is also a paper of aluminum-plastic composite packaging film delaminating status mainly means the paper layer of middle level. The analysis because the paper fiber layer in the middle of the fusion compressive strength is low, and the moisture content of the paper itself and the cohesion compressive strength.
