Packaging Film Quality Needle Roller Bearing There are probably 2 main issues in this area at present, one is price, quite simply the better the seal ability and robustness of the material the more expensive it is.

The second is the drive to reduce and minimise the packaging material used.

As most packaging materials are a combination of at least two materials and an adhesive layer to hold them together, the quality and control of this manufacturing process can have a big influence on the quality and reliability of the final packaging.

Therefore poor process control can obviously affect the quality of each layer in the film, the thickness and uniformity of each layer, the strength of the bond between them and finally how they are wound on to a core ready for delivery to you the customer.

Sealing Parameters For seal testing purposes, to create a seal between two pieces of material and ensure there are three parameters at work, Time, Pressure and Temperature.

Time is normally controlled by the throughput of the machine and can normally only be adjusted by slowing the speed of the packaging machine, so it is usually the last resort when trying to improve seal quality.

Pressure is adjustable and can play a vital part in the quality of the seal, too little pressure and the material is not well bonded, too much pressure and the material can be damaged.

This is also complicated by high points in the seal at overlaps in Vertical Form Fill and Seal or Horizontal Flow Wrap Metal Bellows Seal where the longitudinal or fin seal is sealed in the end seal.
