Types of Disposable Lunch Boxes

Plastic disposable lunch box

Disposable lunch boxes made of plastic mainly include PP polypropylene and PS polystyrene, both of which are non-toxic, tasteless and odorless, and PP is softer. Generally, the use temperature of PP is -6 degrees to +120 degrees, so special It is suitable for serving hot meals and hot dishes. It can be heated in a microwave oven, or even cooked in a steam cabinet. The use temperature of modified PP can be controlled from -18 degrees to +110 degrees. The lunch box made of this PP can be heated in addition to In addition to using at 100 degrees, it can also be refrigerated for use.

PS is hard and transparent, but easy to tear. PS starts to become soft when the temperature reaches 75 degrees, so it is not suitable for hot meals. However, PS has good low temperature performance and is a better packaging material for ice cream.

In order to reduce costs, some lunch box factories use PP as the box and PS as the lid. The advantage is that the lid is transparent and the PS is harder, so it can be made of thinner sheets to reduce costs, but consumers must understand two materials for this design. The difference, remember not to put the whole box of lunch together with the lid into the microwave to heat.

Cardboard Disposable Lunch Box

The cardboard snack box is made of 300-350 grams of bleached sulfate wood pulp cardboard as raw material, and is made by die-cutting and bonding or die-cutting, pressing, and shaping through a stamping and forming process similar to sheet metal processing. In order to prevent it from seeping oil or water, it is necessary to coat the surface with a film or apply chemical additives. In the process of production and use, it is non-toxic and has no side effects to the human body. However, the quality requirements for cardboard are higher, and the cost is also increased.

Starch type disposable lunch box

The edible fast food box with starch as raw material, as the name implies, is made of starch plants as raw materials, added with dietary fiber and other edible auxiliaries and kneaded by stirring. Refined by ion chelation and other technologies, the operating temperature is -10 degrees to +120 degrees, so it is especially suitable for serving hot meals and hot dishes. It can be heated in a microwave oven, and can be refrigerated for use.

Pulp molded disposable lunch box

It is made by pulping and purifying wood pulp or reed, bagasse, wheat straw, straw and other annual herb fiber pulp, adding an appropriate amount of non-toxic chemical additives, molding, drying, shaping, shaping, trimming and sterilizing. The aesthetics of the product is not high, and it will also increase the pollution of wastewater.

Plant fiber disposable lunch box

In terms of environmental protection advantages, plant fiber lunch boxes have obvious advantages. It uses plant fibers extracted from straw, rice husks, bagasse, etc. as raw materials, and adds molding agents, adhesives, water-resistant agents and other auxiliaries. After drying, shaping, disinfection and other post-processing. These agricultural scraps can become industrial raw materials and contribute to the comprehensive utilization of agricultural resources.

Degradable plastic lunch box

The raw materials for the manufacture of such disposable lunch boxes are degradable plastics. The so-called degradable plastics mean that a certain amount of additives, such as photosensitizers, starches and other raw materials are added in the production process of plastics. In this way, the degradable plastic products are used up. After being exposed to nature for three months, it can be broken down into pieces from its intact shape, thus improving the environment.

Biodegradable Lunch Box Disposable Lunch Box

Biodegradable disposable lunch box is a relatively advanced environmental protection product.

It uses starch as the main raw material, adds one-year-growing plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast food box. Since starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally decomposed into water and carbon dioxide.

In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment.

The main source of raw starch production can be corn, potatoes, sweet potatoes, cassava and other annual growing plants.

Naturally, most of the raw materials for biodegradable production are food crops, which can completely replace foam lunch boxes without any pollution to the environment.
