The cartridge 10 is implemented as a PGA-modified material.
Preferably, the thickness of the case 10 is 0.3-1.5mm.
It should be noted that the thickness of the case 10 is positively related to the weight of the food, that is, the heavier the weight of the food, the greater the thickness of the case 10, so as to effectively avoid the case 10 being too thin and the food being too heavy, which results in the case 10 being unable to effectively bear the food and being broken. In addition, the thickness of the case 10 is positively correlated with the size of the accommodating space 101, that is, the larger the size of the accommodating space 101 is, the larger the thickness of the case 10 is, so that the case 10 cannot effectively bear food and is broken due to excessive food accommodated in the accommodating space 101 is effectively avoided.
Preferably, the PGA modified material is prepared by blending PGA or PGLA, a toughening material, inorganic powder, an auxiliary agent and the like. Preferably, 70-95 parts of PGA or PGLA, 5-30 parts of toughening material, 0.1-15 parts of inorganic powder and 0.1-5 parts of auxiliary agent.
It will be appreciated by those skilled in the art that PGA is polyglycolic acid or polyglycolide and PGLA is a copolymer of glycolic acid and lactic acid or a copolymer of glycolide and lactide or polyglycolide-lactide, with GA being the predominant component.

Referring to fig. 3, the flexible film cover 20 includes a base layer 21, a barrier layer 22, a waterproof layer 23, and an adhesive layer 24, wherein the barrier layer 22 and the waterproof layer 23 are formed on two sides of the base layer 21, and the adhesive layer 24 is formed on one side of the barrier layer 22 or the waterproof layer 23 away from the base layer 21. The bladder cover 20 is adhered to the case 10 in such a manner that the adhesive layer 24 corresponds to the opening 102.
The substrate layer 21 is implemented as a degradable material and the barrier layer 22 is capable of gas barrier and water resistance. In this way, the design of the base material layer 21 is used to improve the degradability of the soft film cover 20; due to the design of the barrier layer 22, the flexible film cover 20 seals the opening 102 to separate the food in the case 10 from the external air, so as to extend the preservation time of the food, and the barrier layer 22 and the waterproof layer 23 are combined to be double waterproof, so that the situation that the use effect of the flexible film cover 20 is affected due to the penetration of the liquid into the flexible film cover 20 is prevented, and the situation that the liquid penetrates into the flexible film cover 20 and finally into the case 10 is prevented, so that the quality of the food in the case 10 is affected.
