What material is environmentally friendly and safe for crisper boxes

Environmentally friendly and safe materials for refrigerator crisper boxes mainly include food grade plastics, silica gel and 316 stainless steel. Food-grade plastics: Materials such as PP and PE are non-toxic and harmless and safe to the human body. They have good impact resistance and sealing properties, which can effectively prevent food leaks and bacterial growth. Food-grade plastic crisper marked "BPA-free" further ensures product safety. In addition, these plastic materials are light and easy to clean, making them ideal for daily home use.

Qualified food-grade crisper boxes are environmentally friendly and have low safety hazards, while inferior or non-compliant crisper boxes may pose safety risks. Common safety crisper materials include food-grade PP, high-borosilicate glass, and 304/316 stainless steel. These materials are in line with national food safety standards and will not release harmful ingredients during normal use, and their environmental protection is guaranteed.

When choosing the material of refrigerator crisper, PP and PET materials have become common options. Let's first discuss the advantages of PP materials. PP material is famous for its excellent mechanical properties and good heat resistance. Its continuous use temperature can be as high as 110-120 ° C. It has excellent chemical stability and can withstand most chemical substances. It also has good water resistance and electrical insulation. However, PP has relatively weak impact strength at low temperatures and is prone to aging.

It is recommended to use food-grade PP, silicone, and glass preservation boxes for refrigerator preservation. These three materials are safe, non-toxic, low-temperature resistant and have good sealing properties, and are suitable choices. Food-grade PP material (polypropylene) 1) is safe and non-toxic. It has passed the certification of food contact materials. It is resistant to high temperatures of 120 ° C and low temperatures of-20 ° C. It can be used in refrigerators for freezing and refrigeration. 2) It is light and durable, light in weight, and has strong resistance to falling. It is suitable for putting daily ingredients such as leftovers and fruits.

Among the crisper boxes, AS material crisper boxes are more prominent in terms of environmental protection and safety. The following is a detailed explanation of the environmental protection and safety of the material of the container. PP material, the container PP (polypropylene) is a widely used plastic material that has good heat resistance, chemical resistance and mechanical properties. In the field of crisper boxes, PP material is widely used because of its non-toxic, odorless, high transparency and easy processing.

[One article revealed] Are these common plastic materials really safe when contacting food?

1. Safety: PP (polypropylene) raw materials are environmentally friendly and corrosion-resistant, and are safe to be used as food packaging containers.

2. Like the common PP polypropylene plastic, it is often used to make microwave oven lunch boxes. It has good temperature resistance and chemical stability. It is a commonly used material in the food packaging field and has guaranteed safety. However, in some special scenarios, food-grade plastics may also pose health hazards: in high temperature environments: some plastics will undergo chemical changes at high temperatures, precipitating harmful substances.

3. The safety of common plastic materials in contact with food is a matter of great concern, because the materials of food packaging and containers are directly related to people's health and safety. The following are some common plastic materials and their safety analysis in food contact: Polyethylene terephthalate (PET): PET is one of the most common food grade plastics and is widely used in mineral water bottles, beverage bottles, etc.

4. Plastic food contact materials do have many potential safety hazards, mainly including additive migration, monomer residues, microbial contamination and degradation product hazards. The details are as follows: Additive migration plasticizers: Phthalates are commonly used Plasticizers, which can increase the flexibility of plastics. However, when plastic products come into contact with oily or alcoholic foods, plasticizers easily migrate out.

Which is more suitable for making lunch boxes, ABS or PC?

I think choosing PC or ABS depends on the specific application needs. If transparency and high impact resistance are required, PC is a more suitable choice; while if higher hardness and wear resistance are required, ABS may be more suitable. In practical applications, composite materials of the two can also be considered to comprehensively leverage their respective advantages. When making material choices, it is best to make informed decisions based on the specific use and specific performance requirements of the product.

It should be noted that although these plastics are called "food grade", not all plastics are suitable for long-term high temperature use. Medical plastics have stricter requirements in terms of chemical stability and biological safety to ensure that the material components are harmless to the human body. Common medical plastics include PVC, PE, PP, PS, ABS and PC.

Not all ABSs meet food grade standards and require a brand selection when purchasing.

What are the characteristics of ABS plastic? Characteristics: Good comprehensive properties, high impact strength, chemical stability, good electrical properties. It has good fusion property with 372 plexiglass and can be made into two-color plastic parts. The surface can be plated and painted. It has high impact resistance, high heat resistance, flame retardant, enhanced, transparent and other levels. The fluidity is a little worse than HIPS, better than PMMA, PC, etc., and has good flexibility.

Just name a few and hope they will help you. Computer shell: ABS Because ABS is a copolymer of three monomers: acrylonitrile (A), butadiene (B) and styrene (S), ABS resin maintains the excellent electrical properties and ease of processing of styrene. It also increases elasticity, strength (properties of butadiene), heat and corrosion resistance (excellent properties of acrylonitrile), and has high surface hardness and good chemical resistance.

What food grade plastics are there?

Grade "02" is HDPE (High Density Polyethylene), which is often used in cleaning products, bath products, medicine bottles and skin care product packaging. This plastic can withstand high temperatures of 110 ° C and is suitable for food packaging. However, containers should not be recycled because they are difficult to clean thoroughly. The "03" grade is PVC (polyvinyl chloride), which is mainly used for raincoats and building materials. This plastic easily releases toxic substances under high temperatures and oily environments and is not suitable for use in food packaging.

There are seven grades for food-grade plastics. The higher the grade, the greater the hardness of the material. Level one material: PET (polyester). PET is often used to make mineral water bottles and carbonated beverage bottles. This material can withstand a maximum temperature of 70 ° C and is suitable for holding warm or cold drinks. Exposure to high temperatures may release substances harmful to health. Level two material: HDPE (High Density Polyethylene).

Food-grade plastics mainly include the following types: Polyethylene (PE): Polyethylene is a safe food packaging material and is widely used to make plastic bags, containers and bottle caps. It does not release harmful substances into food and ensures the safety of food. Polypropylene (PP): Polypropylene is another plastic commonly used in food packaging. It has good heat resistance and chemical stability, and is suitable for making food containers, tableware and bottle caps.

PP (polypropylene) is a common food-grade plastic material with high heat resistance and chemical corrosion resistance, so it is widely used in the field of food packaging. For example, some microwave utensils and food containers are made of PP materials. PE (polyethylene) is also a commonly used food grade plastic material with good low temperature resistance, so it is often used for packaging refrigerated foods.

The six levels of food-grade plastic labeling have their own characteristics. Level 1 PET: Common in mineral water bottles, beverage bottles, etc. This material is resistant to 70 ° C, is easily deformed, cannot be recycled, and may release harmful substances after 10 months of use. Grade 2 HDPE: It is mostly used for packaging cleaning products and bathing products. It can withstand high temperatures of 110 ° C and is marked as food that can be used to hold food, but it is not easy to clean thoroughly and is not recommended for recycling.

Common uses of HDPE (high density polyethylene): cleaning products, bathing product packaging, etc. HDPE is a commonly used plastic packaging material for cleaning products and bathing products, and is also used in food-grade plastic bags common in supermarkets and shopping malls. This material can withstand temperatures up to 110 ° C, and plastic bags used for food can safely hold food.
