Material for producing natural degradable deep-cavity thin-wall soft bottle for tableware and soft bottle thereof

Abstract

The invention relates to a material for producing a soft bottle for natural degradable deep-cavity thin-walled tableware, and the soft bottle. The material consists of the following components in weight percentage: 85 to 90 percent of polylactic acid ester, 9 to 14 percent of polyethylene terephthalate, and the balance being additive of the polyethylene terephthalate. The soft bottle produced from the material has the characteristics of good glossiness, tensile strength and ductility, innocuity, no pungency, good biocompatibility, biodegradability and biological absorption and the like. The soft bottle does not pollute the environment and cannot distribute poison gas and cause pollution in combustion. The soft bottle has the advantages of higher limit oxygen index (LOI 24-29), good self extinguishing after ignition, low smoke development in combustion, better flame retardant property, and the same combustion value as that of paper incineration. The material is a sustainable ecological fiber. In the process of using the soft bottle, the advantages of health and innocuity, no need of cleaning, environmental protection, and natural degradation are achieved.

Description

technical field [0001] The invention relates to a material for making a soft bottle for natural degradable deep-cavity thin-walled tableware and the soft bottle. Background technique [0002] At present, known baby feeding bottles are made of plastic or glass. The milk is in direct contact with the inner wall of the bottle. Plastic feeding bottles will release the harmful substance BPA after a certain period of use, while feeding bottles made of glass are easily broken. Both plastic feeding bottles and glass feeding bottles are difficult to clean, and they will pollute the environment after being discarded and cannot be degraded. Contents of the invention [0003] The object of the present invention is to provide a kind of material that is used for feeding bottle liner, and the deep-cavity thin-walled soft bottle for tableware made of this material, that is, the feeding bottle liner has the actual effect of natural degradability. [0004] The present invention also provi...
