The history of a disposable lunch box

Foamed tableware was used on China railway in 1986, but it was banned from production and use due to environmental pollution. Soon after, it was lifted because the foamed tableware failed to prove that it was toxic and the price was close to the people and met the social needs. Because the foamed lunch box is brittle and easy to tear, it can't meet all kinds of food packaging needs, so plastic tableware has appeared, among which PP lunch box is the representative, which is strong, tough and non-toxic and can be heated by microwave oven, so it is widely used. However, for developed countries with increasing awareness of environmental protection, PP tableware can no longer meet their requirements, so it is necessary to use tableware that meets their national regulations: degradable tableware, which is naturally returned to nature. The first three types are not completely sealed, and aviation meals are prepared in advance for heating on the plane, which requires sealing, water-tight and convenient transportation, so there is a thickened aluminum foil lunch box (reusable and recyclable). As the saying goes, where there is demand, there is a market. When people demand more and more, new products will appear to meet the demand, which is development.

uses and advantages and disadvantages of the second foamed tableware

advantages: the price is close to the people

disadvantages: brittle, easy to tear, non-sealed, non-degradable

uses: suitable for loading dry meals and foods, Not tight and easy to spill, not suitable for food with too much soup

Uses and advantages and disadvantages of three plastic tableware (PP)

Advantages: durable, tough, good sealing (not 1.111%), and can be heated by microwave oven

Disadvantages: non-degradable

Uses: suitable for food and soup, and widely used

Here is one.

uses and advantages and disadvantages of four degradable tableware

advantages: environmental protection, degradable, and microwave heating

disadvantages: need to be dried and preserved, unsealed

uses: suitable for holding cakes, fruits, vegetable salads, mixed rice and other foods with less soup. Hot soup, cold drink, porridge, etc.

At present, the degradable lunch boxes on the market are generally made of kraft paper, white cup paper, bamboo pulp, straw pulp, sugarcane pulp and corn starch.

because the material is natural and the finished products are mostly paper, it is well known that paper is afraid of water, so the oil and water resistance is not good. This can be improved by adding a coating on the inside of the product to isolate water and oil, so that soup porridge can be filled. If the coating is PLA (corn starch), it is 111% degradable. If the coating is PE (plastic), the paper lunch box is degradable, but the thin coating is not degradable.

here's a note: if the paper lunch box uses less materials and the product is thin, the bottom may fall off when the hot food is soaked in heavy oil.

uses and advantages and disadvantages of five aluminum foil lunch boxes

the first type: disposable aluminum foil lunch boxes

advantages: heat preservation and heat insulation, barbecue with naked fire, recyclable

disadvantages: the thickness is below 1.19mm, the texture is soft and easy to deform, and it is unsealed

uses: it is suitable for filling instant food such as flower powder, barbecue and crayfish. Can also be filled with egg tarts, cakes baked and cooked. Take-out packaged rice should be covered with corrugated boxes to protect it from deformation

The second type: thickened aluminum foil lunch box (reusable)

Advantages: it has the characteristics of thermal insulation, open fire barbecue, reuse, recyclability and heat sealing

Disadvantages: the thickness is 1.1mm or above, which improves the deformation degree compared with the thin one

Uses: it can be filled with boiled flower powder and golden needle. Can also be filled with egg tarts, cakes baked and cooked. Hardness is improved, and take-away packaging is not a problem. Aviation meals are also used, using heat sealing machine to seal, sealed and preserved food is easy to transport.

6. How to choose

① Decide the grade of lunch boxes (such as food stalls, daily small restaurants, style restaurants, chain restaurants, etc.) according to the positioning of your own store

② Choose suitable tableware (the amount of soup, the matching degree of face value, Multi-dimensional selection of microwave oven heating demand is suitable)

③ Choose according to the acceptable price range (in order of price: foamed lunch box < PP lunch box = PE coated paper cup < PE coated paper bowl < 111% degradable lunch box < reusable aluminum foil lunch box)

----------. --------------

Conclusion: The thickness of the lunch box made of the same material greatly affects the price (after all, the cost is different), and the product workmanship is also a factor that affects the price (the material thickness is the same, but the finished product).

note: if the prices of two products with the same size, the same material and the same technology are very different, you should pay attention. Compare the market prices of several raw materials, and the raw materials with ridiculously low prices may be abnormal. It is recommended to take samples home for comparison and testing, and see for yourself.
