Description
Technical Field
The invention relates to the field of food packaging, in particular to a self-sealing food packaging bag and a using method thereof.
Background
A food packaging bag is a packaging design, and is convenient for keeping food fresh and storing in life, so that a product packaging bag is produced. The food packaging bag refers to a film container which is directly contacted with food and is used for containing and protecting the food. Food packaging bags can be divided into, according to their application ranges: common food packaging bags, vacuum food packaging bags, aerated food packaging bags, poached food packaging bags, steamed food packaging bags and functional food packaging bags.
The food packaging bag has the following functions:
physical protection: the food stored in the packaging bag needs to be prevented from being extruded, impacted, vibrated, subjected to temperature difference and the like.
And (3) protecting the shell: the outer casing can separate food from oxygen, water vapor, dirt, etc. and the leakage prevention is also one essential factor for packing design. Some packages incorporate desiccants or deoxidizers to extend shelf life. Vacuum packaging or evacuating air from the bag is also the primary method of food packaging. Keeping food clean, fresh and safe within the shelf life is the primary function of the packaging bag.
And (3) packaging the same: the insertion of small articles of the same kind in a package is a good way to save volume. The powder and granular objects need to be encapsulated.
Conveying information: packaging and labeling tell people how the package or food is to be used, transported, recycled or handled.
Marketing: marketing often uses package labels to encourage potential buyers to purchase goods. Packaging designs have been a phenomenon of great weight and constant change over the decades. Marketing communication and flat surface design are applied to exterior packaging boxes and (for some reasons) bright spots for sales displays.
Safety: packaging can play an important role in reducing the risk of transport safety. The packaging bag can also prevent food from being returned to other commodities. Food packaging can also reduce the likelihood of food being consumed by theft. Some food packages are very secure and have anti-counterfeiting marks that protect the benefits of the merchant from loss. The packaging bag can be provided with laser marks, special colors, short message authentication labels and the like. In addition, in order to prevent theft, the food packaging bag is pasted with an electronic monitoring label, and the consumer takes the outlet of the store to demagnetize.
Convenience is as follows: the package may be provided with features to facilitate adding, loading, unloading, stacking, displaying, selling, opening, repacking, using and recycling.
Partial control: a single package helps to keep track of the overall situation accurately. For example, the amount of the salt stored in the package can be known. It also facilitates the calculation of sales, such as the delivery and recycling of milk bottles by dairy companies, rather than for the filling of consumers themselves.
The existing food packaging bag usually comprises two layers of sealing, wherein one layer of sealing is an outer layer of glue sealing and has a tearing opening on the surface, which is a destructive opening mode, the other layer of sealing is an inner layer of clamping and sealing, the clamping and sealing can be repeatedly used, after food is taken and taken, the food is clamped together again and still has a sealing effect, but in this way, in the actual operation process, the two clamping components need to be aligned, but the aligning surface is larger because the clamping components usually penetrate through the cross section of the whole packaging bag, which brings difficulty to clamping and sealing, meanwhile, the clamping components are usually of slender structures, so that the alignment difficulty is further increased, partial misalignment is often failed, partial air leakage is caused, the sealing performance is influenced, in addition, in actual operation, the situation that sealing is forgotten often exists, so that food is quickly rotten, and the waste rate is increased.
Disclosure of Invention
1. Technical problem to be solved
Aiming at the problems in the prior art, the invention aims to provide a self-sealing food packaging bag and a using method thereof, which are characterized in that after the packaging bag is opened, can spontaneously approach each other without the action of external force, simultaneously drives the two self-sealing adsorption pads at the inner side to approach each other, under the attraction of the two self-sealing blocks, the plurality of the mother sealing blocks and the son sealing blocks are mutually connected in an extrusion way, thereby leading a plurality of female seal blocks and the coated soft magnetic strip to be in close contact and realizing the self-sealing inside and outside, reducing the manual contraposition process, reducing the sealing difficulty and improving the sealing convenience compared with the prior art, meanwhile, the situation that a user forgets to seal after taking food is effectively avoided, the effect of food spoilage due to accidents is reduced, and the food waste rate is reduced.
2. Technical scheme
