CN2402474Y - High transparent composite covering film - Google Patents

Abstract

The utility model relates to a high transparent composite cover film. The utility model has a shape which is corresponding to a box opening of a food fresh-keeping box and is provided with a tearing edge. The cover film is adhered on the box opening of a fresh-keeping box filled with food. The cross section of the cover film has a layer-shaped structure, and the layer-shaped structure comprises a nylon layer, adhesive glue, a shrink film, the adhesive glue, an obstruction film, the adhesive glue and a thermosol film from top to bottom. The utility model has the functions of ultraviolet ray resistance, air oxidation resistance and temperature resistance; when the utility model is matched with the existing five-layer composite fresh-keeping box, the fresh-keeping ability is further improved; the obstruction performance is good, and the shrinkage is smooth after the film is sealed; patterns can be easily printed on the reverse surface, which is sharp, bright and transparent; food pasteurization can be carried out.

Description

High transparent compound epiphragma

The utility model relates to food preserving box, and concrete is a kind of high transparent compound epiphragma as fresh-keeping lid.

Along with the economic construction development, living standards of the people improve, the variation more of the kind of listing food, some food is contained in the crisper and sells, we disclose a kind of " high transparent layer crisper " in Chinese patent 99205146.0, be fit to fruit jellies food and meat, the fresh-keeping packaging of greengrocery food, fresh-keeping effect is better, the time of guaranteeing the quality is longer, and thereafter, we find that the epiphragma supporting with it also leaves some room for improvement, improve preservativity, increase new kind.

The purpose of this utility model provides a kind of high transparent compound epiphragma, and is supporting with existing five layers of crisper, further improves preservativity, prolongs the food preserving time, easy to use, healthy.

The purpose of this utility model is achieved in that

A kind of high transparent compound epiphragma, the box mouth of shape and food preserving box is corresponding and take off the limit, and this epiphragma is adhered on the box mouth of the crisper that food is housed, and it is characterized in that: its cross section is bedded structure, from top to bottom is followed successively by:

1. nylon layer;

2. adhesive glue;

3. shrink film;

4. adhesive glue;

5. Obstruct membrane;

6. adhesive glue

7. thermosol film.

Described nylon layer can shrink nylon ONY/MS for the center;

The material of described shrink film can be polyethylene from high pressure process LOPE;

The material of described Obstruct membrane can be ethenol copolymer EVOH;

The material of described thermosol film is a resin;

Described adhesive is nontoxic clear binder.

The utility model has following actively useful effect:

1. seven layers of compound epiphragma have uvioresistant, oxidation in the anti-air, and the resisting temperature effect, it and existing five layers of composite fresh-keeping box are supporting, can further improve preservativity, and the time of guaranteeing the quality is long, and its fresh-keeping effect and can are close;

2. this epiphragma barrier property is good, and the heat-sealing mouth is firm, and sealing is strong;

3. it is smooth that seven layers of epiphragma seals after-contraction, easily at the back face printing picture and text, and clear clear transparent, good decorating effect;

4. can carry out the pasteurize of food;

5. can be used for the fresh-keeping of various food, be specially adapted to the fresh-keeping of fruit, jelly, pudding dish.

Now in conjunction with the accompanying drawings:

Fig. 1 is a profile schematic diagram of the present utility model;

Fig. 2 is that the A-A of epiphragma analyses and observe enlarged diagram among Fig. 1.

Accompanying drawing number:

1. epiphragma 101. nylon layers 102. adhesive glues

103. shrink film 104. adhesive glues 105. Obstruct membranes

106. adhesive glue 107. thermosol films

2. food preserving box

Please refer to Fig. 1 Fig. 2, the transparent compound epiphragma 1 of height of the present utility model, the box mouth of shape and food preserving box 2 is corresponding and take off limit 108, and this epiphragma 1 is adhered on the box mouth of the crisper 2 that food is housed, the cross section of described epiphragma 1 is bedded structure, from top to bottom is followed successively by: nylon layer 101; Adhesive glue 102; Shrink film 103; Adhesive glue 104; Obstruct membrane 105; Adhesive glue 106; Thermosol film 107.

During enforcement,

Described nylon layer can shrink nylon ONY/MS for the center that Japanese middle cotton company sells;

The material of described shrink film can be the polyethylene from high pressure process LOPE of the Yanshan Mountain, Beijing chemical company production;

The ethenol copolymer EVOH that the material of described Obstruct membrane can be sold for Japanese middle cotton company;

The material of described thermosol film is a resin;

Described adhesive is nontoxic clear binder.
