Abstract
The invention discloses a preparation method of a fresh-keeping bag. The method comprises the following steps of: preparing a plastic film of which the thickness is 0.05 mm into the fresh-keeping bag, wherein the size of the fresh-keeping bag can be determined by the amount of stored products; and inlaying a silicon window on the bag body of the fresh-keeping bag, wherein the silicon window is directly adhered to the bag body at the temperature of between 105 and 110 DEG C and under the pressure of 75 kPa, the adhering time is 1 second, and the area of the silicon window can be calculated according to the air permeability, the respiration intensity of fruits and the filling amount of the fruits and vegetables. The preparation method has the advantages that the method is convenient to operate, the fresh-keeping bag prepared by the method can inhibit the respiration intensity of the fruits and the vegetables, reduce the activity of internal enzymes of the fruits, keep the freshness of the vegetables and the fruits, and simultaneously can reduce the gas releasing times, thereby being capable of reducing energy consumption and bag damages during operation, reducing the cost, and ensuring the quality of the stored products.
Description
Technical field
The present invention relates to a kind of preparation method of packaging material, is a kind of preparation method of freshness protection package specifically.
Background technology
Preservative film, freshness protection package are the plastic packing products of the class fresh-keeping foodstuff used always of people, there are a lot of families all to be unable to do without them now, as if people feel to have used just safety, reliable of its food, and still, this preservative film, freshness protection package itself just are difficult to make the people relieved sometimes, polyvinyl chloride for example, be called for short PVC, this material also can be used for packaging for foodstuff, but it has certain influence to the security of human body, PVC fresh-preserving film contains carcinogen, and is bigger to human body harm; Though polypropylene preservative film and polyethylene preservative film are nontoxic, but make through fixed length, cutting, heat-sealing bag basic skill or training preface by homogenous material, the freshness protection package permeability that adopts this method to make is poor, the preserving fruit and vegetable utilizing time short, in fruit vegetables storing period, to regularly open the sack sack ventilative, will certainly increase labour intensity like this, and the quality of fruits and vegetables can not get guaranteeing.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of preparation method of freshness protection package in order to overcome the deficiencies in the prior art, and the freshness protection package permeability that this method is made is good, can improve the freshness of fruits and vegetables.
Technical scheme: in order to solve the problems of the technologies described above, the preparation method of a kind of freshness protection package of the present invention, this method is as follows:
(1) plastic sheeting of 0.05～0.1mm is made freshness protection package; How many sizes of freshness protection package can be determined according to the quantity of stored product;
(2) on the bag of freshness protection package, inlay the silicon window.
Adopt the silicon window can make film to CO
2Transmitance be O
25-6 doubly, be N
28-12 doubly, so fruits and vegetables needed O in respiratory
2Can slowly penetrate from the silicon window, and the CO that discharges
2Then can automatically spread out with ethene from the silicon window, thus the fresh keeping time of raising fruits and vegetables.
In step (2), the silicon window is that 105～140 ℃, pressure are directly to be bonded under 75～80kPa on the bag in temperature, and the bonding time is 1～3 second.
Beneficial effect: compared with prior art, advantage of the present invention is easy and simple to handle, and the freshness protection package that adopts this invention to make can suppress the respiratory intensity of vegetables, fruit, the activity of the inner enzyme of reduction fruit, the freshness of maintenance vegetables, fruit; Can reduce simultaneously the venting number of times, thus can reduce operate in energy resource consumption with a damage bag phenomenon, reduce cost, guarantee the stored prod quality.
The specific embodiment
Further illustrate the present invention below in conjunction with specific embodiment, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment 1: the preparation method of a kind of freshness protection package of the present invention, and this method is: the plastic sheeting of 0.05mm is made freshness protection package, and how many sizes of freshness protection package can be determined according to the quantity of stored product; On the bag of freshness protection package, inlay the silicon window, the silicon window is that 105～110 ℃, pressure are directly to be bonded on the bag under the 75kPa in temperature, the bonding time is 1 second, the area size of silicon window can be calculated according to the containing quantity of air penetrability, fruits respiratory intensity and fruits and vegetables, and concrete computing formula is: S=M*R

Embodiment 2: the preparation method of a kind of freshness protection package of invention, and this method is: the plastic sheeting of 0.1mm is made freshness protection package; On the bag of freshness protection package, inlay the silicon window, the silicon window is that 135～140 ℃, pressure are directly to be bonded on the bag under the 80kPa in temperature, the bonding time is 3 seconds, and the area size of silicon window can be calculated according to the containing quantity of air penetrability, fruits respiratory intensity and fruits and vegetables.
Embodiment 3: the preparation method of a kind of freshness protection package of invention, and this method is: the material film of 0.08mm is made freshness protection package; On the bag of freshness protection package, inlay the silicon window, the silicon window is that 120～125 ℃, pressure are directly to be bonded on the bag under the 78kPa in temperature, the bonding time is 2 seconds, and the area size of silicon window can be calculated according to the containing quantity of air penetrability, fruits respiratory intensity and fruits and vegetables.
Claims (2)
1. the preparation method of a freshness protection package is characterized in that this method is as follows:
(1) plastic sheeting of 0.05～0.1mm is made freshness protection package;
