Abstract
The utility model provides an easy-to-tear cover material and belongs to a cover material relating to a packaging material of convenient food or drinks with paper as a basic material. The utility model has a following technical proposal that; the cover material uses copperplate paper as the basic material; the upper surface of the copperplate paper is provided with an ink layer; the lower surface is provided with a low-density polyethylene bonding layer. The outer surface of the bonding layer is closely adhered with an aluminum foil layer; the outer surface of the aluminum foil layer is provided with an adhesive layer; the outer surface of the adhesive layer is provided with a heat sealing layer. The utility model can make packaging materials easily sealed or easily torn to keep the integrity of the cover materials so as to overcome the problems existing in the background technology.
Description
Technical field
It is the instant food of base material or the lid material of drink packing thing that the utility model belongs to a kind of relating to paper.
Background technology
Before the utility model is realized, be to adapt to environmental protection requirement, be widely used in originally instant food or drink as: the polystyrene foamed of bowl instant noodle (PSP) by withdraw from use gradually, the employing in generation is the packing of above-mentioned food or drink with paper.In present known technology, because lid material and packing material bond comparatively firmly, during loam cake that people in use unpack, easily tear and cover material, thereby destroyed the integraty of this lid material, it is very inconvenient to use.
Summary of the invention
The purpose of this utility model is: a kind of covering material torn off easily is provided, is salablely can open easily again thereby make packing material, and can keeps covering the integraty of material, thereby overcome the problem that exists in the above-mentioned background technology.
Technical solution of the present utility model is: it is base material that described lid material adopts art paper, the aluminium foil layer that adheres in the intimate of the ink lay of the upper surface of art paper, the low density polyethylene (LDPE) adhesive linkage of lower surface, described adhesive linkage, the bond layer of aluminium foil layer outside face have hot sealing layer on the outside face of described bond layer.
The utility model can adopt conventional coating machine to process during fabrication.Described hot sealing layer can be harmless modified low-density polyethylene be material, its thickness can be 20 μ.
Appended drawings 1 is in the structural representation accompanying drawing of the present utility model: art paper 1, ink lay 2,, adhesive linkage 3, aluminium foil layer 4, bond layer 5, hot sealing layer 6.
The specific embodiment
Ink lay 2 is printed in the upper surface of art paper 1 with conventional approach, be coated with the adhesive linkage 3 that one deck is material with the low density polyethylene (LDPE) with conventional approach equally on the lower surface of art paper, close attachment one deck aluminium foil layer 4 on the outside face of this adhesive linkage, bond layer 5 is coated on the outside face of aluminium foil layer, hot sealing layer 6 is a material with harmless modified low-density polyethylene, and evenly be coated in a usual manner on the outside face of bond layer, its thickness can be 20 μ.
Claims (2)
1, a kind of covering material torn off easily, its structure is base material with the art paper, the low density polyethylene (LDPE) adhesive linkage, close attachment that comprise ink lay, the art paper lower surface of art paper upper surface are in the aluminium foil layer of polyethylene adhesive linkage outside face, the bond layer of aluminium foil layer outside face is characterized in that at the outside face of described bond layer hot sealing layer being arranged.
2, covering material torn off easily according to claim 1 is characterized in that described hot sealing layer can be harmless modified low-density polyethylene, and its thickness can be 20 μ.
