To
obtain multi-layer polymer films, including the use of aluminum foil
and paper the following lamination technologies are used: "wet", "dry", under
pressure, using a molten mass, co-extrusion, which is a separate
technology of obtaining multilayer films. Traditionally, the term "laminate" refers to materials produced by connecting ready films.
In the "dry" laminating most commonly used two-component polyurethane adhesive with a solvent. Polymerization
of polyurethane begins after mixing the components, such as polyester
with isocyanate, and increases during the evaporation of the solvent in a
tunnel dryer. Accelerate
the polymerization, and thus increase the resistance of the connection
layer laminate sought by heating the laminated cylinder. The
technology of dry lamination with solvent traditionally used in the
production of laminates, which are the mutual connection of plastic
films, such as: PA / LDPE, PET / LDPE, including in the form of
metallized films and plastic films with aluminum foil.
On dry laminator GF series offsetting cylider is directly glued to bind two
materials , featuring fast working speed and good trim of the laminated
products . The machine is suitable for two-layer or multi-layer binding
of various rolled film materals such as PET, glass paper , BOPP , mylon ,
CPP ,CPE , PE , aluminum foil and paper . So the superb packing
material is thus made .
Properties:
1.Unwinding and rewinding are controlled by magnetic powder brake and magnetic powder clutch .
2.The
drying system is of separate 3 sections at constant temperature and
secondary drafting , resulting in energy saving and perfect drying .
3.The first base-material unwinding adopts automatic deviation rectification to ensure trim side and correct gluing .
4.The
binding compression roller and gluing compression roller are
pnematically activated to ensure trim side and correct gluing .
5.The binding compression roller and gluing compression roller are pnematically activated to ensure even pressure.
6.The main motor adopts frequency-changing speed regulation , with stable running and energy saving.
7.Large-size cast iron base-plate is used to guarantee preciseness of the whole machine and easy installation .
