Abstract
The utility model discloses a multifunctional biaxial tension polypropylene hot-sealing film, which relates to a compound film flexible packing material, and adopts a film structure compounding three layers into a whole body, wherein the middle layer is a core layer (1) of PP (Polystyrene) homopolymer and the other two layers are surface layers respectively arranged at the two sides of the core layer (1). The thickness of the core layer (1) is 14-25 micrometers; the thickness of the surface layer (2) is 1.5-3 micrometers; and the thickness of the surface layer (3) is 2-3.5 micrometers. The multifunctional biaxial tension polypropylene hot-sealing film is a novel film packing material compounded by BOPP (Biaxially-oriented Polypropylene) and provides a new function for BOPP compound material. The multifunctional biaxial tension polypropylene hot-sealing film can not only satisfy the use requirements of conventional compounding, printing and hot sealing for BOPP film gluing, but also realizes the direct compound with a plurality of other materials without using a binder, and the compound firmness completely satisfies the use requirements; downstream processing procedures are simplified; moreover, energy sources are greatly saved; no organic solvents volatilize to pollute the environment during the producing process; and products environment-friendly and healthy.
Description
Technical field
The utility model relates to a kind of multi-functional BOPP heat sealing film flexible packing material.
Background technology
Bidirectional stretching polypropylene film is BOPP, and it is the abbreviation of " Biaxially OrientedPolypropylene ".This production of products principle is: proportioning is former, auxiliary material is sent into feed bin, high-pressure delivery to extruder plastifies into melt; Melt filters through pipeline transmission, filter; Be assigned to die head through runner, become the casting sheet through cold cydariform, thereafter through longitudinal stretching, cross directional stretch system film; Film becomes parent roll at traction unit through corona treatment, cuts into finished film at last.
The utility model content
The utility model provides a kind of multi-function double-way oriented polypropylene (BOPP) heat sealing film; It is a kind of BOPP packing film new material; It not only can satisfy the requirement that the conventional gluing of BOPP film is compound, print and seal use; And be suitable for directly compound with other multiple storeroom, and do not need adhesive, realized the variation of BOPP heat sealing film function.
For addressing the above problem, the utility model adopts following technical scheme: it is three layers of compound membrane structure that becomes one; One deck is the sandwich layer (1) of PP homopolymers wherein, and two-layer in addition is the top layer, is arranged at the two sides of sandwich layer (1) respectively.
The thickness of said sandwich layer (1) is the 14-25 micron, and top layer (2) thickness is the 1.5-3 micron, and top layer (3) thickness is the 2-3.5 micron.
The utility model is directly compound with BOPP film and other multiple storeroom, and does not need adhesive, and compound fastness satisfies instructions for use fully; Not only the downstream manufacturing procedure is abbreviatied; And practiced thrift the energy significantly, production process organic solvent-free volatilization contaminated environment, product environmental protection, health.
The new advantage of comparing with other complex class BOPP film of this practicality is mainly reflected in following aspect: applied widely: can be compound with multiple material, like aluminium foil, plastics, paper, glass etc., be used to produce compound package material; Need not any adhesive; The storeroom combined strength bination is firm, satisfies instructions for use fully; Cut down the consumption of energy and environmental protection; Significantly save production cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: sandwich layer 1, top layer 2,3.
The specific embodiment
As shown in Figure 1, multi-function double-way oriented polypropylene heat sealing film, it is three layers of compound membrane structure that becomes one; One deck is the sandwich layer (1) of PP homopolymers wherein, and two-layer in addition is the top layer, is arranged at the two sides of sandwich layer (1) respectively; Its mesexine (2) is non-processing layer; Top layer (3) is functional layer and treated side, and its mesexine (2) is non-processing layer, and top layer (3) are functional layer and treated side.
The thickness of said sandwich layer (1) is the 14-25 micron, and top layer (2) thickness is the 1.5-3 micron, and top layer (3) thickness is the 2-3.5 micron.
The utility model is through three-layer co-extruded and form above-mentioned top layer, sandwich layer; Compare with common bidirectional stretching polypropylene film; Sandwich layer (1) is identical with top layer (2) composition, and sandwich layer (1) main component is additives such as PP homopolymers and a small amount of bass special 905,2335, and top layer (2) are the functional layer macromolecule polypropylene; Top layer (3) is functional layer and treated side, has added the homemade a kind of heat-sealing masterbatch of our company, and main component is shell HDPE 5621D, the CPP of Basel binary heat-sealing material RC213M, 5014, and small amount of thermal melten gel resin etc.
This production of products process: adopt the three-layer co-extruded bidirectional stretching polypropylene film production equipment of the conventional configuration of German Bruckner company or MIT, need not to change any hardware device.Raw material, auxiliary material are sent into feed bin, plastify into melt through high-pressure delivery to extruder, melt passes through pipeline transmission; Filter filters; Be assigned to die head through runner, through biaxial tension operation system film, film becomes parent roll at traction unit through corona treatment thereafter; Parent roll cuts into finished film at last through Ageing Treatment.
The film-forming process mesexine (3) of the utility model has added the homemade functional form masterbatch of our company, can be directly compound in the use with multiple material, like aluminium foil, plastics, paper, glass etc., be used to produce compound package material.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (2)
1. multi-function double-way oriented polypropylene heat sealing film is characterized in that, it is three layers of compound membrane structure that becomes one; One deck is the sandwich layer (1) of PP homopolymers wherein, and two-layer in addition is the top layer, is arranged at the two sides of sandwich layer (1) respectively.
2. multi-function double-way oriented polypropylene heat sealing film according to claim 1 is characterized in that the thickness of said sandwich layer (1) is the 14-25 micron, and top layer (2) thickness is the 1.5-3 micron, and top layer (3) thickness is the 2-3.5 micron.
