First of all, the probability of making disposable tableware with bottle material is very low, I have contacted customers who are not disposable tableware and seldom encountered the bottle material added to it. Tableware is mainly pp material, corresponding to the pp bottle material, in the process of processing will inevitably appear some yellowing, and then injection molding transparent products is impossible. If the processing of other colors, with the bottle particles wasted, directly with other colors of recycled materials to do more cost-effective. In addition, cost reduction can be used in addition to recycled materials, you can also add filler masterbatch, the cost is lower. So for large companies, to pass the various tests of food, plus hanging bottle particles is not a good choice, for small businesses, from an economic point of view is not a good choice.
The use of bottle material is more suitable for mixing into the low-end material to improve performance, such as 315 said the woven bag, children's toys and so on. China's plastics market, Hebei and Shandong, that part of the original low-end market is dominated by the pursuit of low prices, the use of these scraps to make toys is really possible.
Additionally, the production of bottles of material to be reprocessed into products, the middle of at least two processing, the temperature between 150-200, can indeed kill most bacteria, but definitely not necessarily no danger. The key question at one end, how this material from the hospital out? As well as food, toys and other industries how to strengthen the regulation is more important issue. Guangdong side of the export of toys in addition to rosh, reach and other conventional testing, but also need to industry standard testing, etc., why we do not need self-sales? Recycled materials have long been an industry, not the question of whose heart is black, but a lot of testing and supervision links on the lack of today's situation.
Secondly, the hazards are not necessarily there.
The plastic needs to be processed to about 300 degrees, and no virus should be able to carry that, though only for about 6-8 seconds. As for the plastic itself, I don't think there should be a problem, for example, we at Formosa Plastics (the plant that makes plastic pellets) have grades 1250,1450T,1560TX, of which, 1250 is for organizers, 1450 is for specialized lunch boxes, and 1560 is medical grade for syringes. But! A lot of times, the difference between pp plastics is basically just processing performance, and I suspect that even if you use the 1250 to make syringes, the biggest problem is mostly lack of transparency, lack of processing stability, etc., and it should work fine on its own. Similarly, 1560 for lunch boxes, my biggest concern may be that the high temperature resistance is not necessarily enough. Summary:In terms of hazards, one is 300 degrees, 6-8 seconds can kill the virus, one is, medical-grade plastics can withstand high temperatures, one is the hospital chemicals have no residue in the inside (generally no, otherwise it will produce steam, there will be fog).
