Abstract
The utility model discloses a capping membrane for an aluminum-coated polystyrene one-piece cup. The capping membrane comprises a blocking layer, and is characterized in that a surface layer is arranged on the blocking layer, wherein a bonding layer is arranged between the surface layer and the blocking layer; a heat sealing layer is arranged below the blocking layer; a bonding layer is arranged between the blocking layer and the heat sealing layer; the surface layer is made of polyester; the blocking layer is made of aluminum-coated polyester; the heat sealing layer is made of polyethylene-vinyl acetate; and the bonding layer is made of polyurethane. According to the capping membrane for the aluminum-coated polystyrene one-piece cup, the blocking layer is made of the aluminum-coated polyester which has good light resistance, good oxygen resistance and moisture resistance, and is easy to tear, the surface layer is made of the polyester with good printability, and the heat sealing layer is made of the polyethylene-vinyl acetate which has good heat sealing ageing extent and is easy to open, and so the comprehensive requirements can be satisfied.
Description
Technical field
The utility model relates to composite membrane, and specifically a kind of polystyrene connecting cup of aluminizing is with sealing epiphragma.
Background technology
The polystyrene connecting cup product is comparatively novel packaging for foodstuff mode, and it is a disjunctor that its marketing method is generally the 4-8 cup, and every glass is an independent packaging, seal at present the more employing aluminium foil of epiphragma as barrier layer, although barrier property is pretty good, difficult control on easy-to-rupture, and also cost is higher.Except above-mentioned requirements, the sealing epiphragma also requires printing good, and has the easily property opened after adding hot-seal, and the sealed membrane that homogenous material is made can't satisfy above-mentioned requirement.
Summary of the invention
The purpose of this utility model is to propose a kind of polystyrene connecting cup of aluminizing sealing epiphragma that can satisfy above-mentioned requirements.
The purpose of this utility model is achieved in that the polystyrene connecting cup of aluminizing of the present utility model is with sealing epiphragma, it comprises barrier layer, it is characterized in that at barrier layer the top layer being set, between top layer and the barrier layer adhesive layer is arranged, under barrier layer, hot sealing layer is set, between barrier layer and the hot sealing layer adhesive layer is arranged, polyester is adopted on above-mentioned top layer, barrier layer adopts aluminum polyester, and hot sealing layer adopts polyethylene-vinyl acetate, and adhesive layer adopts polyurethane.
The polystyrene connecting cup of aluminizing of the present utility model is with sealing epiphragma, because barrier layer adopts resistance light, resistance oxygen, resistance moist good, the aluminum polyester that easily tears simultaneously, the good polyester of printing is adopted on the top layer, therefore polyethylene-vinyl acetate that hot sealing layer adopts heat-sealing always to spend, easily open can satisfy above-mentioned comprehensive requirement.
Description of drawings
Fig. 1 is the structural representation of polystyrene connecting cup with the sealing epiphragma of aluminizing of the present utility model.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, the polystyrene connecting cup of aluminizing of the present utility model is with sealing epiphragma, it comprises barrier layer 3, it is characterized in that at barrier layer 3 top layer 1 being set, and between top layer 1 and the barrier layer 3 adhesive layer 2 is arranged, 3 times hot sealing layer 5 is set at barrier layer, between barrier layer 3 and the hot sealing layer 5 adhesive layer 4 is arranged, polyester is adopted on above-mentioned top layer 1, and barrier layer 3 adopts aluminum polyester, hot sealing layer 5 adopts polyethylene-vinyl acetate, and adhesive layer 2 and adhesive layer 4 adopt polyurethane.
