As consumers pay more and more attention to health, people pay more attention to the health of the materials used in the box itself. Hygienic and safe materials, harmless to human body, such as PC materials, PE materials and PP materials, now the more common preservation box materials are PP materials. Plastic fresh-keeping boxes should not be put into microwave ovens and ovens because plastic can produce harmful substances at high temperatures. In addition, the tempered glass fresh-keeping box may self-explode when it meets extreme cold and extreme heat. At present, the fashionable and green fresh-keeping box is heat-resistant glass fresh-keeping box. Below is a small knitting of disposable environmental protection tableware. Let's understand the correct use of disposable convenience lunch boxes.

不同的形狀存放不同的東西，使用更加方便。除了常見的四方形、長(zhǎng)方形、圓形，還有專為野餐設(shè)計(jì)的套裝等，讓生活變得更加簡(jiǎn)單方便。四方形打包盒：密封性能，適合存放食物，能防止冰箱出現(xiàn)異味，適合存放各種佐料、剩食、剩下的罐頭、水果、蔬菜。便于放在冷藏箱、冷凍箱、微波爐使用，也可以用于其他用途。

Different shapes store different things and make it more convenient to use. In addition to the common square, rectangle, round, there are also special picnic suits designed to make life more simple and convenient. Square packing box: Excellent sealing performance, suitable for storing food, can prevent the refrigerator odor, suitable for storing all kinds of condiments, leftovers, the remaining cans, fruits, vegetables. It is convenient for use in refrigerators, freezers and microwave ovens, and can also be used for other purposes.

長(zhǎng)方形打包盒：適合存放熏肉、肉類食物。由于有接水板，因此易于存放有水分的食物。大容量長(zhǎng)方形保鮮盒適合保存水果、蔬菜和海鮮等。

Rectangular packing box: Suitable for storing bacon and meat food. It is easy to store food with water because of the water receiving board. Large capacity rectangular fresh-keeping box is suitable for preserving fruits, vegetables and seafood.

圓形打包盒：適合長(zhǎng)期存放各種佐料、水果罐頭、雜糧、堅(jiān)果、茶等食物，便于放在冷藏箱、冷凍箱、微波爐使用。長(zhǎng)圓形設(shè)計(jì)適合在野游時(shí)存放飲料、兒童牛奶和各種雜糧、堅(jiān)果和茶等。

Round packing box: Suitable for long-term storage of all kinds of spices, canned fruits, miscellaneous grains, nuts, tea and other foods, easy to put in refrigerators, freezers, microwave ovens. The circular design is suitable for storing drinks, children's milk and various grains, nuts and tea during field trips.

高筒打包盒：適合于存放面條、黃瓜等長(zhǎng)條形食品，由于高筒保鮮盒的高度尺寸比一般保鮮盒要高，在加工工藝上對(duì)模具尺寸及退模要求高，因而市場(chǎng)上能生產(chǎn)高筒保鮮盒的廠家不多，產(chǎn)品也相對(duì)較少。

High-cylinder packing box: Suitable for storing noodles, cucumbers and other long strip food. Because the height of the high-cylinder fresh-keeping box is higher than that of the general fresh-keeping box, the requirement of die size and demoulding is high in processing technology, so there are not many manufacturers that can produce high-cylinder fresh-keeping box on the market, and the products are relatively few.
