The hottest paper cup new national standard avoids

  • Detail

The new national standard of paper cup avoids the import of printing ink

the new measures will prevent the import of paper cup from leaving blank to avoid drinking ink

tomorrow, the national standard of paper cups will be officially implemented. From this national standard numbered gb/t (hereinafter referred to as the national standard), it is noticeable that there should be no printed patterns within 15 mm from the cup mouth to the cup body and within 10 mm from the cup bottom to the cup body. This means that the paper cups we use in the future are no longer full-color

at the same time, the national standard also stipulates that paper cups should not have peculiar smell, should not be made from recycled materials, and should not be artificially added with fluorescent brighteners

France called many paper cup manufacturers late. Many insiders and even manufacturers said that the national standard will increase costs. In the specific operation, the requirements of the national standard and customers must be taken into account

France visited some wholesale markets and supermarkets in the morning and found that the national standard was about to be implemented, but the Sanwu products without production date, manufacturer, shelf life and other information were still on sale

the focus of the industry's response is not to leave blank. The printing method is the key.

Zhang Juan (a pseudonym) is the head of a large paper cup manufacturer in Beijing. Her customers include some state-owned banks and large state-owned enterprises. About 500000 paper cups are produced every day

Zhang Juan introduced that at present, there are two kinds of pattern printing methods on paper cups: offset printing and watermark. Offset printing is bright in color, layered and visually beautiful, but because offset printing contains substances such as lead to varying degrees, if the current printing method is adopted, the paper cup body is full of color, and excessive use will certainly be harmful to the body

watermark is water-based printing, also known as flexo printing. Because there are few toxic organic solvents in water-based ink, it will not have adverse effects on human health and the environment when used. It is a good choice for paper cup printing

paper cup printing directly affects the health of users. Non load mechanism: it is composed of four parts: load device, load adjustment, force sensor and displacement sensor. However, there are not many requirements for printing methods in the national standard. Zhang Juan said

as for the provisions of the national standard for leaving blank, manager Liu of another paper cup manufacturer also said that the key is to see which printing method is used, and the distance from which the pattern cannot be printed is not of great significance. The selection of safe food grade printing materials has little impact on human body

According to Zhang Juan, the cost of offset printing is much lower than that of watermark. The cost of offset printing is 50 to 60 yuan per page. The watermark version is calculated by square centimeter. One square centimeter costs 3 to 50 cents, and one plate costs about 500 yuan. In this way, the cost of plate making alone is nearly 10 times lower

in addition, in terms of appearance beauty, offset printing is better than watermark. The pattern color of offset printing is very bright and clear, while watermark cannot achieve the clear effect of offset printing

after all, doing business depends on the market, and the requirements of customers must always be considered. If customers have requirements for clear patterns, beautiful and good-looking, low price, etc., they can only use offset printing, and there is no explicit provision in the national standard that offset printing cannot be used. Zhang Juan said

manager Liu analyzed from the perspective of raw materials. The cost of different raw materials varies greatly. A good cup paper is pure wood pulp base paper, which costs about 10000 yuan per ton, while a cheap one costs only 5000 or 6000 yuan per ton, or even lower. Others use bamboo pulp and reed pulp as raw materials, which is relatively cheap and saves a lot of costs

insiders admit that raw materials and printing are the main factors that affect the health of users. Cheap raw materials and low-cost printing are not strictly stipulated in the new national standard of paper cups, or even have no corresponding requirements, which will make some bad manufacturers exploit loopholes in order to save costs

the process is not satisfactory

raw material paper contains brightener. The paper cup is lying on the gun

raw materials. In order to avoid the generation of toxic solvents, the national standard stipulates that the paper cup should not have peculiar smell, recycled materials should not be used, the additives used in raw materials should comply with the regulations, and fluorescent brightener, industrial paraffin, industrial talc powder and other additives that are not within the scope of use specified by the state cannot be used in the production and processing of paper cups

in this regard, Zhang Juan admitted that fluorescent brighteners will not be added when large paper mills produce paper cup base paper, but there will be some residues when the production is changed to production, so it can not be completely avoided, as long as it is not excessive, there will be no safety problems

as for the addition of fluorescent brightener, Zhang Juan also said that this has nothing to do with the paper cup factory. The paper cup factory cannot add brighteners. It must be in the paper factory, because the paper cup factory buys all the formed paper. How can it be added at will
