Many clients in customized packaging bags, vacuum bags, in particular, will worry about the vacuum packing bag without wrinkle problem. Why do vacuum packing bag wrinkle? Guangzhou farce bags manufacturer to explain to you, the vacuum packing bag wrinkled reason consists of the following nine o ''clock.
The vacuum packing bag wrinkle reason one: the base material thickness is not uniform, bao hou differ too much.
The vacuum packing bag wrinkle reason 2: the base material roll deflection.
Vacuum packing bag wrinkled three reasons: excessive or insufficient amount of glue in, interlayer sliding occurs; Uneven glue can also cause the emergence of local buckling.
Vacuum packing corrugate four: the cause of insufficient adhesive is dry, residual solvent is too much, small, sticky relay after composite of two kinds of displacement of the base material.
Vacuum packing bag wrinkled reason 5: composite film winding directly, without enough cooling or cooling high temperature soft composite membrane wrinkle easily.
Vacuum packing bag wrinkled because six: composite pressure Settings.
Vacuum packing corrugate seven: the cause of improper tension control, and uncoordinated and winding tension does not match.
Vacuum packing corrugate 8: the cause of the guide roller is not parallel.
Vacuum packing corrugate 9: the cause of the guide roller surface is not clean, sticky there is foreign body, or guide roller surface is not flat, a pit, scratch, dent, etc.
