一次性塑料餐盒大多是以石油中提煉的聚苯乙烯為質(zhì)料，聚苯乙烯是一種運(yùn)用很廣的高分子材料，具有熔點(diǎn)較高、可塑性高、生產(chǎn)簡(jiǎn)潔等，因此成為生產(chǎn)一次性餐盒的常用材料?，F(xiàn)在，市場(chǎng)上的餐盒品類繁多，質(zhì)量參差不齊。一次性環(huán)保餐具廠家為您解說更多事項(xiàng)！

Most disposable plastic lunch boxes are made of polystyrene extracted from petroleum. Polystyrene is a widely used polymer material with high melting point, high plasticity and simple production. Therefore, it has become a common material for the production of disposable lunch boxes. Now, there are many kinds of lunch boxes on the market, and the quality is uneven. The manufacturer of disposable environment-friendly tableware explains more for you!

購買時(shí)要留意以下幾點(diǎn)：看密封性。一般餐盒應(yīng)密封在塑料包裝袋中，包裝袋不該有破損，包裝不嚴(yán)密的餐盒容易受到環(huán)境的污染，衛(wèi)生得不到保證。

Pay attention to the following points when purchasing: see the sealing. General lunch boxes should be sealed in plastic packaging bags, which should not be damaged. The loosely packed lunch boxes are vulnerable to environmental pollution, and their hygiene cannot be guaranteed.

看外包裝，要仔細(xì)檢查包裝標(biāo)志上是否標(biāo)示了"產(chǎn)品名稱、生產(chǎn)者廠名、廠址、產(chǎn)品履行規(guī)范、生產(chǎn)日期、保質(zhì)期、衛(wèi)生許可證"等規(guī)定要標(biāo)示的內(nèi)容，如果標(biāo)志內(nèi)容標(biāo)示不全或許不規(guī)范，則這樣的餐盒就不要購買了。

Look at the outer package, and carefully check whether the package label indicates the contents required to be marked as "product name, manufacturer name, factory address, product performance specification, production date, shelf life, hygiene license". If the label contents are incomplete or not standardized, do not buy such lunch boxes.

看盒身，餐盒盒身的色澤應(yīng)均勻、概括清晰，盒口不該有顯著的洼陷、起皺。看盒口，留意盒口平整、潤滑，無廢邊、毛刺，杯身應(yīng)清潔通明，厚薄均勻，無雜質(zhì)、氣泡、水紋，無魚眼僵塊等現(xiàn)象。

Look at the box body. The color of the lunch box body should be uniform and clear. The mouth of the box should not have significant depressions and wrinkles. Look at the opening of the box and note that the opening of the box is flat and lubricated, free of waste edges and burrs. The cup body should be clean and bright, with uniform thickness, without impurities, bubbles, water marks, fish eyes, and other phenomena.

一次性環(huán)保餐盒是指一次性使用的包裝物品用的盒子，這種包裝盒盡管叫一次性包裝盒，但因?yàn)槠滟|(zhì)料，包裝盒能夠重復(fù)多次使用，現(xiàn)在市場(chǎng)上的一次性包裝盒大多是由橡膠注塑工藝一次性成型的一次性包裝盒。

The disposable environmental protection lunch box refers to the box used for disposable packaging. Although this kind of packaging box is called disposable packaging box, because of its material, the packaging box can be used repeatedly. Most of the disposable packaging boxes on the market now are disposable packaging boxes formed by rubber injection molding process.

一次性餐盒均選擇契合環(huán)保PP新資料，PP塑料餐盒（用質(zhì)料出產(chǎn)、透明）因?yàn)榫哂?、無色、無臭、熔點(diǎn)較高、可塑性高、可回收、包裝密封度好、出產(chǎn)簡(jiǎn)便及相對(duì)成本較低特色，因而成了制作一次性快餐盒的主流資料。

All disposable lunch boxes are selected according to the new environmental protection PP materials. PP plastic lunch boxes (produced with materials and transparent) have become the mainstream materials for making disposable fast food boxes because of their non-toxic, colorless, odorless, high melting point, high plasticity, recyclability, good packaging tightness, simple production and low relative cost.

功能特色：一次性環(huán)保注塑餐盒為PP資料。PP的密度小、強(qiáng)度、剛度、硬度耐熱性均優(yōu)于低壓聚乙烯，耐120攝氏度高溫，-20攝氏度低溫。常見的酸、堿有機(jī)溶劑對(duì)它幾乎不起作用，可用于食具。PP是一種半結(jié)晶性資料，它比PE要更堅(jiān)固并且有更高的熔點(diǎn)，放在水里煮也是沒有問題的。

Functional features: disposable environment-friendly injection molding lunch box is PP material. PP has low density, strength, stiffness, hardness and heat resistance, which are better than low pressure polyethylene, and can withstand 120 ℃ high temperature and - 20 ℃ low temperature. Common acid and alkali organic solvents have little effect on it and can be used for tableware. PP is a semi crystalline material, which is stronger than PE and has a higher melting point. It is no problem to boil it in water.

一般的一次性餐盒都是選用食品級(jí)PP資料的，PP塑料是不吸收微波的，因而它能夠在微波爐內(nèi)做烹調(diào)器皿。一次性環(huán)保注塑餐盒不只方便有用，而且能夠?qū)⑹澄锓珠T別類地寄存，也可疊放在一起。一次性環(huán)保注塑餐盒密封度高，滴水不漏成了人們選擇PP餐盒的重要因素。關(guān)注我們http://m.88dyk.com，了解更多！
