Description
Technical Field
The utility model relates to a food package technical field specifically is a two-sided stretch film vacuum packaging.
Background
The marinated eggs are cooked eggs processed by various seasonings or meat juices. The marinated eggs are popular food in the egg products operated by the delicatessen and are popular with people. Present traditional spiced egg packing adopts plastic envelope evacuation packing mostly, because the most meeting of stew in soy sauce food is in the bag with a small amount of thick gravy encapsulation, when tearing the wrapping bag, very easily appear the condition that thick gravy spattered outward, and the application of force direction has uncertainty moreover, forms great opening easily and causes the thick gravy in the bag to spill over, can pollute both hands and clothing, especially under the outer anhydrous abluent condition of going out, is unfavorable for keeping sanitation and hygiene.
SUMMERY OF THE UTILITY MODEL
In view of the problem that exists among the prior art, the utility model provides a two-sided tensile membrane vacuum packaging, the technical scheme of adoption is, including having the bag body of last membrane and lower membrane, the bag body has the sealed chamber of egg shape, and the outline of the bag body is big end down's egg shape, and the outside in sealed chamber is the seal area, and the top of the bag body is equipped with easily takes off the mouth, and last membrane and lower membrane in easily taking off the mouth do not bond, go up the membrane and all adopt the tensile membrane that has the suction bubble structure down, form through the evacuation between the suction bubble structure of last membrane and the suction bubble structure of lower membrane sealed chamber, go up and form through the heat-seal bonding between membrane and the lower membrane seal area, go up membrane and lower membrane and all stretched into the ellipse unanimous with sealed chamber.
Further, the upper film and the lower film may be stretched to the same or different depths.
Further, when the stretching forming depth of the upper film and the stretching forming depth of the lower film are different, the upper film forming depth may be lower, or the upper film forming depth may be lower.
As an optimized technical scheme of the utility model, be equipped with the transition district between easy-to-tear mouth and the sealing district, the last membrane in easy-to-tear mouth and the transition district is not bonded with lower membrane, separates by the bonding line between easy-to-tear mouth and the transition district and comes.
As an optimized technical scheme of the utility model, easy taking off is crescent to downwarping, and the transition region is arc narrowband structure.
The utility model has the advantages that: the utility model discloses in, from easily taking off a mouthful department will go up the lower membrane from the centre separately, the packing of easily taking off a mouthful department is not torn, can block the thick gravy that upwards splashes, has reduced the situation that thick gravy splashes outward, is favorable to keeping the sanitation and hygiene when edible, in addition, bag external contour is egg-shaped, and the appearance is novel pleasing to the eye, adopts two-sided tensile membrane, and the product after the packing can be hugged closely and is deposited, and occupation space is little.
Drawings
Fig. 1 is a schematic structural view of the double-sided stretch film vacuum package of the present invention;
fig. 2 is a schematic view from above of fig. 1.
In the figure: 1-bag body, 10-sealing cavity, 11-upper film, 12-lower film, 2-sealing area, 3-easy-to-uncover, 4-transition area and 5-bonding line.
Detailed Description
The technical solution of the present invention will be described in detail by the following specific examples.
As shown in fig. 1 to 2, the double-sided stretch film vacuum package includes a bag body 1 having an upper film 11 and a lower film 12, the bag body 1 has an egg-shaped sealed cavity 10, the outer contour of the bag body 1 is egg-shaped with a small top and a large bottom, a sealed area 2 is outside the sealed cavity 1, an easy-open port 3 is provided at the top of the bag body 1, the upper film 11 and the lower film 12 in the easy-open port 3 are not bonded, the upper film 11 and the lower film 12 both use stretch films having a bubble-absorbing structure, the sealed cavity 10 is formed between the bubble-absorbing structure of the upper film 11 and the bubble-absorbing structure of the lower film 12 by vacuum pumping, the sealed area 2 is formed between the upper film 11 and the lower film 12 by heat-sealing bonding, and the upper film 11 and the lower film 12 are both stretched into an oval shape consistent with the sealed cavity 10.
Further, the upper film 11 and the lower film 12 may be formed to have the same or different stretch depths.
Further, when the upper film 11 and the lower film 12 are formed to different depths, the upper film 11 may be formed to be shallow and the lower film 12 may be formed to be deep, or the upper film 11 may be formed to be deep and the lower film 12 may be formed to be shallow.
As an optimized technical scheme of the utility model, be equipped with transition zone 4 between easy-to-tear mouth 3 and the seal area 2, last membrane 11 and lower membrane 12 in transition zone 4 do not bond, are separated by bonding line 5 between easy-to-tear mouth 3 and the transition zone 4. In the operation process, the size of the opening is easy to control because the transition area buffers the sharp applied force.
As an optimized technical scheme of the utility model, easy uncovering 3 is crescent to the downwarping, and transition zone 4 is arc narrowband structure.
The utility model discloses a theory of operation: when the package needs to be opened, the upper film and the lower film are uncovered from the middle part from the easy-to-uncover part, the acting force is slowly acted on the sealing area through the bonding line above the transition area, the sealing cavity for containing the marinated eggs is opened, and if a small amount of marinade is splashed upwards, the marinade is blocked by the package in the transition area and the easy-to-uncover part.
Although the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge range of those skilled in the art, and modifications or variations without creative efforts are still within the scope of the present invention.
