Ningbo Yi sheng Plastic Cup With the continuous development of science and technology, environmental pollution has become more and more serious. The international community is calling for environmental protection. First of all, we must first understand what we usually use disposable plastic milk tea cup material which? Here, I will briefly explain that the materials used in the tea cups usually produced by the factory are PP, PET and PS. For the future technological development, if these materials can be degraded, it is a great benefit for environmental protection. Degradable plastics refer to plastics that add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) during the production process, and have reduced stability and are more easily degraded in the natural environment. Photosensitizers are incorporated into plastics to gradually degrade the plastic under sunlight. It belongs to the earlier generation of degradable plastics. Its disadvantage is that the degradation time is difficult to predict due to sunshine and climate change, and thus it is impossible to control the degradation time. Under the action of microorganisms, it can be completely decomposed into low molecular compound plastics. Its characteristics are convenient storage and transportation, as long as it is kept dry, no light is needed, and it has a wide range of applications. It can be used not only in agricultural plastic film and packaging bags, but also in medicine. With the development of modern biotechnology, biodegradable plastics have received more and more attention and have become a new generation of research and development hotspots.
Under normal circumstances plastic milk tea cups filled with tea or fresh, frozen, in the case of no ice will not break the cup. The customer told us that in other manufacturers' custom milk tea cups, there was no ice in the refrigerator, and there was only one reason: The pp material used by the manufacturer during the production of the cup was recycled material instead of the new pp material. The recycled material is also the second-hand material. The cups produced are not strong enough to be brittle and will crack when the temperature is low. The milk tea cup produced by the normal brand-new pp material will not produce the cracking effect in the absence of ice, and we can ensure that the flying factory can fly.
The production of disposable pet cup and the printing process are completely different from the production process of pp plastic cups. The biggest difference between the two is that: paper cups are first formed after printing; plastic cups are first formed and printed. First of all we have to buy raw materials, that is, paper. The paper mentioned here is not the kind of A4 paper we see, but a kind of paper with a large volume and a large volume; the purchased paper must be laminating with a laminating machine; the paper cup after laminating is slit through the slitter. , Slit into rectangular paper; after the paper is cut, the printer prints the logo pattern required by the customer; after the customer's logo is printed, the die cutting machine cuts the paper into fan-shaped paper. We all know that the paper cup is fan-shaped;
