紙質(zhì)餐盒以紙為基材,表面覆以石蠟、聚乙烯涂層等,用于食品包裝或冷熱飲料和冷熱食品的容器。因?yàn)槭羌堎|(zhì)材料,所以可以回收利用。通過(guò)掩埋或焚燒,不會(huì)造成嚴(yán)重的環(huán)境污染,具有很高的環(huán)保價(jià)值。
Paper lunch boxes are based on paper and coated with paraffin and polyethylene. They are used for food packaging or containers for hot and cold beverages and food.

紙餐盒的分類
Classification of paper lunch boxes
紙餐盒按加工材料可分為卡紙餐盒、紙漿模壓紙餐盒、銅版紙餐盒三大類。其中,銅版紙餐盒較為常見(jiàn);按容量分為大、中、小三類。紙餐盒給人們的日常生活帶來(lái)了便利,深受人們的喜愛(ài)。使用量逐年增加,尤其是在快餐店。
According to the processing materials, paper lunch boxes can be divided into three categories: cardboard lunch boxes, pulp molded paper lunch boxes, and coated paper lunch boxes. Among them, coated paper lunch boxes are more common; According to the capacity, it is divided into three categories: large, medium and small. Paper lunch boxes have brought convenience to people's daily life and are deeply loved by people. The usage is increasing year by year, especially in fast food restaurants.
一次性紙餐盒
購(gòu)買紙質(zhì)飯盒
Buy paper lunch boxes
一般一次性紙餐盒根據(jù)其外觀應(yīng)密封在塑料包裝袋中,包裝袋不得破損。包裝不嚴(yán)密的紙質(zhì)餐盒很容易被環(huán)境污染,衛(wèi)生也無(wú)法保證。選擇比較堅(jiān)固的紙質(zhì)飯盒,盡量選擇壁厚較硬的盒子。您可以用手輕輕擠壓產(chǎn)品的兩側(cè),即可大致了解其承重性能的好壞。另外,不要選擇外觀過(guò)于白的紙質(zhì)餐盒產(chǎn)品,因?yàn)榭赡軙?huì)出現(xiàn)熒光物質(zhì)過(guò)多的問(wèn)題。
Generally, disposable paper lunch boxes should be sealed in plastic bags according to their appearance, and the bags should not be damaged. Paper lunch boxes with loose packaging are easy to be polluted by the environment, and sanitation cannot be guaranteed. Choose a stronger paper lunch box and try to choose a box with a harder wall thickness. You can squeeze the two sides of the product gently by hand to roughly understand its load-bearing performance. In addition, do not choose paper lunch box products with too white appearance, because there may be too many fluorescent substances.
其次,看標(biāo)志。產(chǎn)品包裝上應(yīng)注明生產(chǎn)廠家名稱、地址、產(chǎn)品執(zhí)行標(biāo)準(zhǔn)、生產(chǎn)日期等。消費(fèi)者應(yīng)盡量選擇近期的產(chǎn)品,因?yàn)榇娣艜r(shí)間越短,產(chǎn)品的污染程度越低。小心購(gòu)買標(biāo)志不全的產(chǎn)品,更不要購(gòu)買“三無(wú)”產(chǎn)品。
Secondly, look at the signs. The name, address, executive standard and production date of the manufacturer shall be indicated on the product package. Consumers should try to choose recent products, because the shorter the storage time, the lower the pollution degree of products. Be careful to buy products with incomplete marks, not to mention "three noes" products.
還有一次性紙餐盒商戶。消費(fèi)者在購(gòu)買一次性紙餐盒時(shí),一定要去大型商場(chǎng)、超市、百貨公司,選擇大企業(yè)生產(chǎn)的品牌產(chǎn)品。
There are also disposable paper lunch box merchants. When buying disposable paper lunch boxes, consumers must go to large shopping malls, supermarkets, department stores and choose brand products produced by large enterprises.
