The invention belongs to the field of composite materials for packaging bags, and particularly discloses a high-air-tightness composite packaging material and a preparation method thereof.
Background
On the basis of the development of the packaging industry, the packaging of articles has also been developed accordingly. The development has progressed from simple paper packaging, to single-layer plastic film packaging, to the widespread use of composite materials. The composite material can ensure that the contents in the package have the characteristics of moisture preservation, fragrance preservation, beauty, fresh preservation, light protection, seepage prevention, shelf life extension and the like, thereby being developed rapidly. The composite material is a composite material with a certain function formed by combining two or more materials through one or more composite processes. Generally, it can be divided into a base layer, a functional layer and a heat-seal layer. The base layer mainly plays the roles of beauty, printing, moisture resistance and the like. Such as BOPP, BOPET, BOPA, MT, KOP, KPET, etc.; the functional layer mainly plays roles of blocking, shading and the like, such as VMPET, AL, EVOH, PVDC and the like; the heat sealing layer is in direct contact with the packaged goods, and has the functions of adaptability, permeability resistance, good heat sealing property, transparency, opening date property and the like, such as LDPE, LLDPE, MLLDPE, CPP, VMCPP, EVA, EAA, E-MAA, EMA, EBA and the like. The composite packaging materials involve many kinds of raw materials, have different properties, have many and complicated problems such as material which can be combined or can not be combined, and material which can be used for bonding, and the like, so that the materials need to be carefully selected to obtain ideal effects. The selection principle is as follows: (1) specifying the objects and requirements of the package. (2) Selecting proper packaging raw materials and a processing method; (3) with the proper adhesive or laminating material. The composite film material in China starts from the end of seventies, and some extruders, film blowing machines and printing machines are introduced from the early stage to the middle stage of eighties to produce simple two-layer or three-layer composite materials. Such as extrusion compounded BOPP/PE, paper/PE, pp/PE; dry-type composite BOPP/PE, PET/PE, BOPP/AL/PE, PET/AL/PE, etc., wherein, in LDPE resin and film, LLDPE with a certain proportion is blended to enhance the strength and stiffness. The packaging method is mainly applied to packaging of instant noodles, biscuits, hot pickled mustard tuber and other foods. Typical coating grade LDPE resins are; IC7A, L420, 19N430, 7500, etc.; blown film grade LDPE resins are: q200, Q281, F210-6, 0274, etc.; the LLDPE resins are: 218w, 218F, FD21H, etc.
In the present bag-making industry, the composite material is also more and more widely used, and how to improve the air tightness of the composite material by selecting a proper composite material proportion and controlling parameters such as speed, temperature, pressure and the like during heat sealing is the focus of the present research.
