Mar. 29, 2019

Here is 8 Inch Clamshell Wholesaler talking about Plastic And Cardboard Disposable Lunch Boxes.

1. Plastic type

Disposable lunch boxes made of plastic are mainly PP polypropylene and PS polystyrene. They are non-toxic, tasteless and odorless. PP is soft. Generally, the PP temperature is -6 degrees to +120 degrees, so it is special. It is suitable for hot meals, can be heated in a microwave oven, or even cooked in a steam cabinet. The modified PP can be used at temperatures ranging from -18 degrees to +110 degrees. The lunch box made of this PP can be heated. It can be placed in the refrigerator for refrigerating use up to 100 degrees.

PS is hard and transparent, but it is easy to tear. PS starts to soften when the temperature reaches 75 degrees, so it is not suitable for hot rice hot dishes, but PS has good low temperature performance and is the best packaging material for ice cream.

In order to reduce the cost, some lunch box factories use PP as a box and PS as a lid. The advantage is that the cover is transparent and the PS is hard. It can be made with thinner sheets to reduce the cost, but the consumer must understand the two materials. The difference, remember not to put the whole box with the lid and put it in the microwave to heat.

2. Cardboard type

The cardboard fast food box is made of 300-350 grams of bleached sulfate wood pulp paperboard and is formed by die-cut bonding or die-cutting pressing and shaping through a stamping forming process similar to enamel processing. In order to prevent oil leakage or water seepage, it is necessary to coat the surface or apply chemical additives. It is non-toxic and has no side effects on the human body during production and use. However, the quality requirements for paperboard are high, and the cost is also increased.
