In order to address the above problem, the technical solution of the utility model is to provide a kind of explosive-proof sealed epiphragma of easily opening of the plastic food-case for heating using microwave, it is characterized in that, comprise successively compound printing basement membrane, adhesive phase and hot sealing layer, it is characterized in that, the gross thickness of described epiphragma is not more than 70 μ m; Described hot sealing layer is three-layer co-extruded modified polyethylene film, and thickness is 40-55 μ m, and it comprises compound successively skin, core layer and internal layer; Adhesive phase is mutually compound with the skin of hot sealing layer.
Preferably, described printing basement membrane is that thickness is that biaxial tension nylon film or the thickness of 15 μ m is the biaxially oriented polyester film of 12 μ m.
Preferably, the thickness of described adhesive phase is 2.5-3.0 μ m.
Preferably, described skin is ldpe resin layer, and thickness is 10-15 μ m.
Preferably, the ldpe resin of the high-density polyethylene resin that described core layer contains 60% percentage by weight and 40% percentage by weight, thickness is 10-20 μ m.
Preferably, the medium density polyethylene of the polybutene resin that described internal layer contains 15-25% percentage by weight, 30-50% percentage by weight and the ldpe resin layer of 25-55% percentage by weight, thickness is 20-25 μ m.
Preferably, when described epiphragma is overlying on plastic food-case, printing basement membrane is positioned at plastic food-case outside; On epiphragma, apart from two longer edge sealing 6-8mm places of plastic food-case, be provided with discontinuity and do not penetrate otch, the length that discontinuity does not penetrate the per pass otch of otch is 5mm, adjacent twice otch be spaced apart 5mm, notch depth is as the criterion to cut off top layer printing basement membrane.
On described epiphragma, apart from two longer edge sealing 6-8mm places of plastic food-case, be provided with 5mm-5mm discontinuity and do not penetrate otch when when heating using microwave gas expansion, cutting part cracking, emit portion gas, prevent the epiphragma food splash that pops, meanwhile, in box, keep certain pressure, food Fast Heating, and moisture can not evaporate in a large number in food, the food after heating still has good mouthfeel.Penetrability otch does not make epiphragma keep complete, has guaranteed the safe and sanitary before food consumption.
Microwave heating of food box prepared by the utility model is easily opened epiphragma, keeps complete sealing before heating, has ensured the safe and sanitary of food in circulation and storage, and without external packing, has reduced total packing cost; When food heats, on epiphragma, the non-otch swelling cracking that penetrates of preprocessing, exits explosion-proof; Epiphragma hot sealing layer easily peel off design, make when edible to facilitate epiphragma easily to open.The utility model epiphragma, manufacture technology is simple, with low cost.

The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1-2, the explosive-proof sealed structural representation of easily opening epiphragma of the plastic food-case for heating using microwave providing for the utility model, comprises successively compound printing basement membrane 7, adhesive phase 8 and hot sealing layer 9, and the gross thickness of epiphragma 2 is not more than 70 μ m.Described hot sealing layer 9 is three-layer co-extruded modified polyethylene film, and thickness is 40-55 μ m, and it comprises compound successively skin 91, core layer 92 and internal layer 93; Adhesive phase 8 is mutually compound with the skin 91 of hot sealing layer 9.Printing basement membrane 7 employing thickness are that biaxial tension nylon film or the thickness of 15 μ m is the biaxially oriented polyester film of 12 μ m.The thickness of adhesive phase 8 is 2.5-3.0 μ m.The skin 91 of hot sealing layer 9 is ldpe resin layer, and thickness is 10-15 μ m; The ldpe resin of the high-density polyethylene resin that core layer 92 contains 60% percentage by weight and 40% percentage by weight, thickness is 10-20 μ m; The ldpe resin layer of the polybutene resin that described internal layer 93 contains 15-25% percentage by weight, the medium density polyethylene of 30-50% percentage by weight and 25-55% percentage by weight, thickness is 20-25 μ m.When epiphragma 2 is overlying on plastic food-case 1, printing basement membrane 7 is positioned at plastic food-case 1 outside; On epiphragma 2, apart from 1 two longer edge sealing 6-8mm places of plastic food-case, be provided with 5mm-5mm discontinuity and do not penetrate otch 3, incision length is 5mm, interval 5mm, and notch depth is as the criterion to cut off top layer printing basement membrane, as shown in Figure 3.
When the heat seal strength of plastic food-case 1 involution that above-mentioned epiphragma 2 and polypropylene PP or polythene PE are made is 10-15N/15mm, (heat-sealing temperature is 150-180 ℃, heat-sealing pressure is 0.35MPa, the heat-sealing time is 1 second), there is good sealing integrity and the easy property opened.
On plastic food-case 1 by epiphragma 2 for heating using microwave, make microwave food, when heating using microwave gas expansion, epiphragma 2 is by jack-up, discontinuity does not penetrate otch 3 swelling crackings, forms a plurality of steam vents 6, emits demi-inflation gas, as shown in Figure 4, prevent the epiphragma 2 food splash that pops; Meanwhile, in plastic food-case 1, still keep certain pressure, make food Fast Heating, and in food, moisture can not evaporate in a large number, keep good taste.
