Machine For Printed Bopp Carton Sealing Tape

Machine For Printed Bopp Carton Sealing Tape

1.  150m/min high speed has already reached the international most advanced level.

2.   Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop, It will reduce the waste.

3.   When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.

Second, the length of the coating section changes, the spacing is unstable:
  1. The length of the segment changes greatly (* is shortened) * The variation of the pitch is small (narrowed)
  2) The gap between the back roller and the rubber roller is too small and too tight.
  3) The tension before and after the mismatch, the unwinding is greater than the winding solution
  1) Cleaning roller
  2) Adjust the diagonal block to a fixed position
  3) Adjust with reference to setting parameters
2. The length of the segment changes greatly (* becomes shorter). The pitch changes greatly (larger).
If the length of the head of the pole piece and the head of the next piece are changed greatly (smaller), the tail change between the two pieces of the pole piece is small, so that the solenoid valve (control roller movement) is inflexible.
3. The length of the segment changes greatly (* becomes longer) * The pitch changes greatly (widening)
1) The surface of the back roller and the rear rubber roller are not clean.
2) There is no pinch roller, there may be no pinch or out of control
3) The tension before and after does not match, the winding is larger than the unwinding solution
1) Cleaning roller
2) Increase the pinch roller
3) Adjust with reference to the setting parameters. 1) The surface of the back roller and the rear rubber roller are not clean.

PET film--

 

(5) PET antistatic film
The world today has entered the information age. Electromagnetic waves of various frequencies and wavelengths fill the entire earth space. These electromagnetic waves will cause different degrees of interference to unshielded sensitive electronic components, circuit boards, communication equipment, etc., resulting in data distortion. Communication is disordered. The static electricity generated by electromagnetic induction and friction on various sensitive components, instrumentation, certain chemical products, etc., such as high voltage discharge due to static accumulation of packaging film, the consequences will be destructive, so the development of antistatic PET packaging film is also very important. The antistatic film is characterized in that an antistatic agent is added to the PET film to form a very thin conductive layer on the surface of the film, and a continuous phase is formed to improve the surface electrical conductivity and cause the generated electric charge to leak as soon as possible. Generally, the surface specific resistance of the antistatic film is ≤109~11 ohms.

(6) PET heat sealing film
Ordinary PET is a crystalline polymer. When the PET film is stretched and oriented, it will produce a large degree of crystallization. If it is heat-sealed, shrinkage deformation will occur, so the ordinary PET film does not have heat-sealing properties. When PET film is used as a commodity packaging, in order to solve the problem of heat sealing, a method of compounding a BOPET film with a PE film or a CPP film is generally adopted, thereby limiting the application of the BOPET film to a certain extent.
In order to solve the heat sealing problem, a three-layer co-extruded heat-sealed PET film, a heat-sealed PET film, has been developed by modifying a PET resin and using an A/B/C three-layer die. Since one side is heat sealable, it can be directly heat sealed and is very convenient to use. The heat-sealed PET film can be widely used in various commercial packaging and card-protecting films
