Problems solved by technology

At present, there are "three no" straws processed from recycled waste plastics on the market. Once these straws are exposed to high temperatures, they will produce toxic substances and endanger your health, especially in the current European market where restrictions on plastic products are relatively strict. , there is an urgent need to produce a new type of environmentally friendly straw that can replace plastic straws

Embodiment 1

[0026] A manufacturing method of a coated regenerated cellulose film straw in this embodiment, first cut the regenerated cellulose film into rolls with a slitting machine to make it into a suitable size; then glue the regenerated cellulose film according to the thickness of the straw , multi-layer compounding, coiling, cutting, and making into tubes of different specifications; and then coating the composite film tubes, and adding a layer of film to the inner and outer layers of the tubes to make them waterproof, oil-proof, and high-temperature resistant. ; Then dry and shape the coated straws and adjust the humidity to obtain disposable coated regenerated cellulose film straws of different specifications. Taking the production of coated regenerated cellulose film straws with a length of 200mm, a thickness of 0.2mm, and a diameter of 6mm as an example, the specific operation steps are as follows:

[0027] (1) Cutting regenerated fiber film: According to the thickness requireme...

Abstract

The invention relates to a preparation method of disposable laminated regenerated cellulose membrane straws. The preparation method comprises the following steps of firstly, cutting and rolling a regenerated cellulose membrane to have a proper size; secondly, carrying out gluing and straw rolling on the regenerated cellulose membrane according to thickness requirements of straws, and then carryingout cutting to prepare straws with different specifications; thirdly, carrying out laminating treatment on the straws; and finally, carrying out drying forming and humidity adjusting on the laminatedstraws to obtain the disposable laminated regenerated cellulose membrane straws with different specifications. The preparation method can be used for preparing the water-proof, oil-water-proof, high-temperature-resistant, sanitary, environment-friendly and degradable straws.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a method for preparing a disposable coated regenerated cellulose film straw. Background technique [0002] The straw is a very inconspicuous thing, but people usually use it when drinking soy milk, milk, beverages, and milk tea. With the improvement of people's awareness of food hygiene, straws as disposable catering supplies have also attracted people's attention. At present, there are "three no" straws processed from recycled waste plastics on the market. Once these straws are exposed to high temperatures, they will produce toxic substances and endanger your health, especially in the current European market where restrictions on plastic products are relatively strict. , urgently need to produce a kind of novel environmental protection straw that can replace plastic material straw. Contents of the invention [0003] Aiming at the above-mentioned technical problems in the pri...
