There are several kinds of adhesives that are used to manufacture protective
film. For example, water-based acrylic, solvent-based acrylic, hot melt adhesive
and natural rubber. The most expensive adhesive may not be the most suitable.
It is important to use the right adhesive on certain surfaces so that we can avoid
residue after removel. Following are some information for different adhesive. It
will help you to konw the adhesives better.
The water-based coating adhesive is emulsified acrylic or polyurethane resin
with water as solvent through specialized equipment. The biggest advantages
are varieties, environmentally friendly and low price. Nowadays most coatings
are water-based glue. For example, general water-based PA, water-based PU,
as well as functional slurry such as oil feeling slurry, wax feeling slurry, color
scraping slurry and so on. Water-based adhesive with its functionality,
environmental protection and low price will be the future direction of coating.
The disadvantages are low film forming ability and poor wash fastness, and PU
can not paste hot glue, not fitting foam, other foam products.
Secondly, solvent-based coating adhesive is dissolved acrylic or polyurethane
with oily solvent such as toluene, DMF, butanone and etc. The advantages are
good film forming ability, good fastness and PU can paste hot glue. This
adhesive is commonly used now. The disadvantage is that it is not
environmentally friendly due to the usage of oily solvent. And the cost is too
high. In order to reduce the cost, some bad oil solvents are used, so it causes
environmental pollution. In addition with further improving national
environmental standards in many countries, so the environment protection
requirements of solvent-based is increasing, too.
Hot melt adhesive is one kind of pressure-sensitive adhesives. Synthetic
rubber, resin, rubber oil and other ingredients are mixed together and heated
into molten state, and then coated on cotton paper, cloth or plastic films or
other substrates, which finally forms the new type of adhesive tape. Low cost
is its biggest advantage. But the viscosity can be easily affected by
temperature, which is a big disadvantage. Hot melt adhesive is mainly used for
various types of box sealing, case sealing, paper packaging, beverage bottle
labels, sealing aluminum foil, flexible packaging and other packaging. It has
strong adhesive to many materials that are difficult to stick, such as various
kinds of PET which are glazed, polished, matte and PP laminated, PP
transparent case, thin film, non-woven products, cosmetics packaging, food
packaging, cigarette packaging, tetra pak drinking packaging, assembling
furniture edge, electronics, automotive interior decoration sealing, car lamps
manufacturing, windscreen assembly, non-woven sanitary towel, diaper, paper
diaper, shoe pad, disposable daily necessities, paper coated composite mark,
label double-sided tape, sticky mouse board, sticky fly paper, wooden floor,
carpet lamination, Band-Aid, medical tape, color boxes packaging, carton
packaging glue and so on. Good thermal stability, no impurities, good
operability and excellent weather resistance are all its advantages. Aluminum
foil sealing hot melt adhesive is unique with waterproof properties.
