Abstract
The utility model relates to a fresh-keeping bag filled with water absorbing cold accumulation agents, which is used for freezing fresh living food. The utility model relates to the fresh-keeping bag which is filled with macromolecule water absorbing material and is sealed all around; an upper layer is a permeable layer made of permeable material, and a lower layer is a smooth layer made of impermeable material. The fresh-keeping bag of the utility model has the advantages of good sealing, difficult water absorbing material out leakage, fresh-keeping food pollution prevention, safety, sanitation, convenient operation and good fresh-keeping effect.
Description
(1) technical field under
The utility model relates to a kind of freshness protection package, particularly a kind of freshness protection package that is filled with the hygroscopic character agent for storage of coldness, is used for freezing fresh and alive food.
(2) background technology
At present, being used for the fresh-keeping of freezing fresh and alive food, generally is to carry out freeze preservation with ice.But directly following deficiency is arranged with ice: the one, ice is fusing easily, gives container easily or is caused damage by fresh-keeping foodstuff.The 2nd, the intensity of ice is big, is difficult for carrying out fresh-keeping to the freezing food of needs parcel.The 3rd, be bonded as one easily between the ice cube, use inconvenient.The 4th, can not recycle.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, and the freshness protection package of a kind of safety and sanitation, easy to use, good refreshing effect is provided.
The utility model is realized by following measure:
The utility model relates to a kind of macromolecule water absorbent material, leak free freshness protection package all around of being filled with, the permeable bed of upper strata for being made by seepy material, the smooth layer of lower floor for being made by impermeable material.
Above-mentioned freshness protection package, described seepy material is preferably nonwoven fabrics; Described impermeable material is preferably transparent plastic film.
Preparation method of the present utility model is, at first seepy material and impermeable material is cut into same size, superimposed after, wherein three limit heat seals sealings in the freshness protection package of then absorbent material that weighs up being packed into, seal another side again.It is the high molecular polymer of 300-600 that absorbent material adopts the imbibition multiple.
Using method of the present utility model is, freshness protection package is put into water, and water enters in the freshness protection package by permeable bed, after the absorbent material imbibition, puts into refrigerator and carries out freezing.Freshness protection package after freezing is placed on to be needed to carry out fresh-keeping on the fresh-keeping food.
Freshness protection package of the present utility model has the following advantages:
1. freshness protection package seals fully, and absorbent material is difficult for leaking outside, and does not pollute fresh-keeping article, safety and sanitation.
2. do not need water filling in the bag, directly freshness protection package is put into water and soaked and to get final product, easy to use.
Absorbent material in the freshness protection package freezing after, fresh-keeping foodstuff is wrapped up in bending arbitrarily, has good fresh-keeping effect.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model
Among the figure, 1 is permeable bed, 2 smooth layers, and 3 is absorbent material.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.
As shown in the figure, be structural representation of the present utility model, freshness protection package be around leak free oblong bag, length and width are respectively 200 centimetres, 150 centimetres, the permeable bed 1 of upper strata for being made by nonwoven fabrics, the smooth layer 2 of lower floor for being made by transparent plastic film.Be filled with 10 gram absorbent materials 3 in the freshness protection package, absorbent material is 450 high molecular polymer for the imbibition multiple.
