6 reasons and solutions for skinny packaging falling off


Slightly careless, after the product is skin-packed , the skin-packing film and cardboard will be separated (in popular terms, the skin -packing is falling off ), which is the biggest and most headache of quality of skin-packing. What is the cause of this problem? How to prevent such problems from happening? When such a problem occurs, is there any good way to save and use the existing cardboard?

 


 
 

The reasons for the inadequate adhesion of the skin-packaging film to the cardboard (the skin-pack packaging falls off) are mainly the following: Reason 1: There is no glue on the skin-packaging film and the skin-packing paper card. Solution: Use paper cassette tape or film tape glue. Cause two: The body - fitting film has adhesive tape, or paper cassette tape adhesive, but the film and paper card are not firmly adhered, resulting in insufficient glue on the film or paper card. Solution: increase the amount of glue to ensure sufficient viscosity. Cause three: The cardboard is not sufficiently vented or the cardboard is not perforated. Solution: Use a special ventilation paper card for the skin, or use a paper card to fill the ventilation holes. Cause four: The surface of the paper card is coated with the wrong glue or oil. Solution: The company's strong-adhesive PP skin-packing film can effectively solve this problem. It can use up the unqualified cardboard and reduce the risk and loss of completely discarding the entire batch of unqualified cardboard. Reason five: The sticky packaging film is generally sticky on the inner layer of the roll film, and the non-adhesive side is used. Solution: Use the glued side for packaging. Cause six: The whole body packaging is sticky in some places, and the cardboard and film are not sticky in some places. This is caused by uneven heating of the body packing machine. Solution: Check whether the heating tube arrangement of the body-fitting machine is reasonable, and whether the heating tube is damaged, and correct it. Friends who have encountered the problem of falling off of skin-packing , please check the seats according to the possible reasons above, and improve as suggested, and the problem can be solved.
