一次性塑料餐盒大多是以石油中提炼的聚苯乙烯为质料，聚苯乙烯是一种运用很广的高分子材料，具有熔点较高、可塑性高、生产简洁等，因此成为生产一次性餐盒的常用材料。现在，市场上的餐盒品类繁多，质量参差不齐。一次性环保餐具厂家为您解说更多事项！

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!

购买时要留意以下几点：看密封性。一般餐盒应密封在塑料包装袋中，包装袋不该有破损，包装不严密的餐盒容易受到环境的污染，卫生得不到保证。

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.

看外包装，要仔细检查包装标志上是否标示了"产品名称、生产者厂名、厂址、产品履行规范、生产日期、保质期、卫生许可证"等规定要标示的内容，如果标志内容标示不全或许不规范，则这样的餐盒就不要购买了。

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，餐盒盒身的色泽应均匀、概括清晰，盒口不该有显着的洼陷、起皱。看盒口，留意盒口平整、润滑，无废边、毛刺，杯身应清洁通明，厚薄均匀，无杂质、气泡、水纹，无鱼眼僵块等现象。

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.

一次性环保餐盒是指一次性使用的包装物品用的盒子，这种包装盒尽管叫一次性包装盒，但因为其质料，包装盒能够重复多次使用，现在市场上的一次性包装盒大多是由橡胶注塑工艺一次性成型的一次性包装盒。

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.

一次性餐盒均选择契合环保PP新资料，PP塑料餐盒（用质料出产、透明）因为具有、无色、无臭、熔点较高、可塑性高、可回收、包装密封度好、出产简便及相对成本较低特色，因而成了制作一次性快餐盒的主流资料。

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：一次性环保注塑餐盒为PP资料。PP的密度小、强度、刚度、硬度耐热性均优于低压聚乙烯，耐120摄氏度高温，-20摄氏度低温。常见的酸、碱有机溶剂对它几乎不起作用，可用于食具。PP是一种半结晶性资料，它比PE要更坚固并且有更高的熔点，放在水里煮也是没有问题的。

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选用食品级PP资料的，PP塑料是不吸收微波的，因而它能够在微波炉内做烹调器皿。一次性环保注塑餐盒不只方便有用，而且能够将食物分门别类地寄存，也可叠放在一起。一次性环保注塑餐盒密封度高，滴水不漏成了人们选择PP餐盒的重要因素。关注我们http://www.1958666.com，了解更多！
