subject: Plastic Film Manufacturers Can Benefit Tremendously From Additives: Experts [print this page] Plastic film manufacturers can benefit tremendously from additives: experts
Modern film manufacturers are often struck between the dilemma of
quality and cost as the virgin polymer has grown increasingly costly
but gives best quality products. On the other hand, using recycled
polymers or filler in polymers is very cost effective but reduces the
quality.
First and foremost, recycled polymers invariably have poorer physical
properties compared to the virgin polymers.
Second, the polymers from two different sources do not meld with each
other easily even if they are of the same plastic.
Last is the problem of moisture retention in recycled polymers.
Recycled polymers are washed and then shredded into smaller pieces
before being processed into granules. This process commonly results in
the polymer retaining a lot of moisture which can create severe
surface defects in the film.
This forces the manufacturers to try out various additives in order to
maintain their products' quality despite the increased filler loading
in their products but the results often fall short of the
