Abstract
The present invention introduces an edible disposable fast-food packaging material which has the technical scheme that linear starch class grains are made into needed semi-finished products through high temperature, high pressure and pressing; atoxic waterproofing thin films are covered on the surface of the semi-finished products. The material can be eaten and can be recovered as feedstuff; a large amount of garbage polluting the environment can not be generated; compared with foamed plastic packages, the present invention has the advantage that the cost is lowered by 80%.
Description
The present invention relates to a kind of packing, especially for the edible harness of fast food food.
The harness of fast food food is modal to be a kind of polyester plastics lunch box, light and handy, convenient, healthy, is disposable tableware.But the discarded back of this type of lunch box material is difficult to reclaim, and becomes the rubbish that railway reaches harbour and tourist site along the line, and As time goes on pollution on the environment will enlarge thus.
In view of the foregoing, the objective of the invention is to design a kind of edible disposable fast food packaging material, make it both can make packing, edible or make feed again, if be dropped, also can come to naught, thereby avoid the environmental pollution that brings by this class rubbish at occurring in nature.
The feature of edible disposable fast food packaging material of the present invention is to adopt amylose class cereal to make raw material, be not less than under the high temperature of 1 kilogram pressure and about 400 ℃ expanded, and Moulding and shaping base, utilize compound film technology to make the ultrathin nontoxic anti-water film of the topped one deck in parison surface again, puffed cereal and extraneous liquid are isolated.
At high temperature, the amylose of α type is cured as β type gelatinized starch structure, and a part of starch is converted into polysaccharide, can be absorbed by the body, indeformable in warm area below 70 ℃, have certain intensity, but the nonreactive power from ocean tides, if adopt the multiple anti-water of film of edible plants glue fat, then cost is more high, also can make both moisture resistances of this material on the puffed cereal surface with the multiple film of non-toxic plastic, direct contact filth not reaches edible hygienic requirements to guarantee it again.Adopt the edible packing of amylose class cereal or its leftover bits and pieces to compare with the packing of polyester material, cost reduces about 80%.If be used for the packing of fast food food, can be according to people's taste similarities and differences, in cereal, add after sugar and salt or other seasonings expandedly, make delicious that it eats.If be used for the packing of other article, can reclaim immediately after then discarded feed pigs, fish etc., be a kind of nutritious fortified feed.Be not eaten, the packing that also is not collected will be softening in the occurring in nature moisture absorption, be hydrolyzed to polysaccharide and texturized fiber, become auxotype organic matter in soil and the current.
Because it is low that the present invention has a cost, edible, the recyclable feed of doing, and can dissolving at occurring in nature, therefore plurality of advantages such as free from environmental pollution, is a new packaging material that is worthy to be popularized.
Embodiment:
Make bowl for snack with edible disposable fast food packaging material of the present invention:
Fig. 1 is the section-drawing with the bowl of edible disposable fast food packaging material making.
Fig. 2 is a bowl lid front view
Front view at the bottom of Fig. 3 bowl
With the common 5000g that cracks rice, send into cereal expanding machine, it is expanded to crack rice under 400 ℃ of high temperature and 1kg pressure, blank after expanded sent in the moulding stamper pressurize, make bowl 100 covers as shown in the figure, wherein, bowl 1 is megaphone-shaped, respectively there is a circular step at the end of bowl body and a mouthful place, the bowl end 2 and bowl lid 3 shapes, size and bowl body 1 adapt, under vacuum, give respectively bowl body and a bowl end, the multiple one deck non-toxic plastic film of bowl cover or food plant glue fat with coating machine, again with at the bottom of the bowl 2 and bowl lid 3 fall into respectively in bowl body on the step, edible fast food rice bowl.
