Why are disposable food fast food boxes made of PP5 material

The disposable food fast-food boxes used in daily life are all made of plastic. There are many types of plastic, and it is generally recommended to use PP5 plastic lunch boxes. Why?

PP5 plastic food fast food box is a plastic box that can be put into the microwave oven, with a melting point of up to 167°. It can be reused after careful cleaning.

It is commonly used in soybean milk bottles, yogurt bottles, and microwave lunch boxes. However, some microwave lunch boxes are made of No. 5 PP, while the lid is made of No. 1 PE, which cannot be placed in the microwave together with the box. It is only suitable for heating soup and should not be used for heating oily foods for extended periods, as the boiling point of oil is above 200°.

When using plastic products, it is important to understand the performance of the product, check for toxicity, and ascertain whether stabilizers have been added. The plastic bottles, food bags, and water bottles sold on the market are all made of polyethylene plastic. They feel smooth to the touch and have a layer of wax on the surface, which is easy to burn. This type of plastic is non-toxic.

PP5 is a mark indicating the material grade. Products made of this material can be directly used for food packaging and can come into direct contact with food. It is generally not recommended to reuse them, as plastic products are relatively thin and prone to damage. It is generally not advisable to store overly hot food in them. However, if they are cleaned thoroughly, they can be reused.

Advantages of food fast food boxes

Whether it's meal boxes or takeout, the use of disposable plastic meal boxes is unavoidable. At the same time, with the introduction of relevant regulations and the increasing awareness of environmental protection among people, more and more food businesses will use environmentally friendly, reliable, and degradable disposable plastic meal boxes for daily packaging.

Advantages of disposable fast food containers

Specifically, the characteristics of tableware should be determined based on the materials used in its production, including cold resistance, heat resistance, microwave resistance, degradability, tensile strength, transparency, strength, hardness, and friction resistance.

Depending on the material, the currently mainstream materials include PET, PP, BOPS, HIPS, etc. These materials can be used for food, and their annual production is increasing. The characteristics of these materials are as follows.

BOPS has good rigidity, high strength, and high PP hardness; good rigidity, heat resistance, and fluidity, as well as good transparency of PET; and good stability, toughness, and friction resistance.

Meanwhile, with the continuous advancement of technology, the technology employed by factories has also undergone corresponding improvements. Thanks to technological advancements, it is now possible to produce more environmentally friendly lunch boxes, which not only reduce environmental pollution but also ensure that the food inside the lunch boxes is not subject to secondary contamination.
