Can the so-called food grade PC materials come into contact with food at high temperatures?

Material safety: Food-grade PC plastic cups are made of polycarbonate (PC) material, which is widely used in the manufacture of plastic containers, such as sports cups, kettles and bottles. When PC plastic is certified as food grade, it is generally considered safe and harmless and can come into contact with food without releasing harmful substances.

Food-grade PC materials can be used to hold edible oil, but temperature conditions need to be paid attention to. First of all, food-grade PC materials (polycarbonate) can be used to come into contact with food, including edible oils, provided they meet food safety standards. This means that from the perspective of material safety, there is no problem in using food-grade PC containers to contain cooking oil.

Food-grade PC is safe under normal use, but needs to avoid high temperatures and strong acid and strong alkali environments. Food-grade PC plastic (polycarbonate) that meets national standards is not toxic in itself and is widely used in milk bottles, cups, crisper boxes and other products. Such materials need to pass GB 4807-2016 food safety testing to ensure that heavy metals, plasticizers and other components do not exceed the standard. When it is used daily to hold cold water or room temperature food, it has extremely high stability.

Food-grade PC materials can be filled with boiling water, but it is not recommended to soak them in boiling water at 100 ° C for a long time. The specific reasons are as follows: The characteristics of PC materials and the risks of bisphenol A PC (polycarbonate) itself is non-toxic, but if bisphenol A is not fully transformed into a plastic structure during the production process, residual bisphenol A may be released at high temperatures. Bisphenol A is an environmental endocrine disruptor. Long-term exposure may increase the risk of cancer, especially for infants and pregnant women.

Is plastic wrap better, pe or pc?

1. In summaryMiaojie plastic wrap pc and antibacterial one are easy to useWhen choosing plastic wrapMiaojie plastic wrap pc and antibacterial one are easy to use, should be based on specificMiaojie plastic wrap pc and antibacterial one are easy to useDetermine whether to use PE or PC material based on the type of food. For vegetables and fruits, PE plastic wrap is a better choiceMiaojie plastic wrap pc and antibacterial one are easy to use; For meat or cooked food, PC plastic wrap is more suitable. At the same time, no matter which material of plastic wrap is used, attention should be paid to correct use methods and temperature control to ensure the safety and taste of the food.

2. Polyethylene (PE) cling film is highly safe, does not contain plasticizers, and has relatively good air permeability.

3. Relevant information points out that PE plastic wrap has passed food contact safety certification and is a relatively safe choice and suitable for the refrigerated storage of ordinary fruits, vegetables and cooked food.

4. Relevant information shows that PE plastic wrap has passedMiaojie plastic wrap pc and antibacterial one are easy to useFood contact safety certification is a relatively safe choice and is suitable for refrigerated storage of ordinary fruits, vegetables and cooked food. 2) PVDC (polyvinylidene chloride) has better heat resistance and sealing properties than PE. It can withstand high temperatures of around 140 ° C and is suitable for microwave heating. However, the price is high, and the production process may have environmental problems. Its use has been reduced in some areas.

What is the difference between antibacterial and preservation aluminum titanium foil and plastic wrap? Which has better preservation effect?

1. Aluminum-titanium foil has strong insulation and can effectively isolate air and moisture. Titanium has antibacterial and antibacterial effects. It can extend the preservation cycle by 15-30 days compared with plastic wrap, and the preservation effect is stronger than that of preservation. Fresh film.

2. Plasticizers in plastic cling film harm the human digestive system. Refrigerators are hotbeds for bacterial growth. Plastic cling film can only isolate bacteria and cannot inhibit the growth of bacteria inside. If the antibacterial is not in place, the preservation will be in vain! Aluminum-titanium foils use aluminum + titanium elements to effectively inhibit bacterial growth; after a 1130-fold reduction of 200 ° C and a high-temperature elimination process for more than 48 hours, they are finally tempered to form an "excellent fresh-keeping material for isolating bacteria and light."

3. Aluminum-titanium foil has strong insulation and can effectively isolate air and water. The titanium element has antibacterial and antibacterial effects. It can extend the preservation cycle by 15-30 days compared with plastic wrap, and the preservation effect is stronger than fresh-keeping film.

4. Preservation effect: Traditional plastic wrap films and plastic bags: Although it can extend the freshness of ingredients to a certain extent, the preservation effect may be limited due to insufficient materials and antibacterial properties. Aluminum-titanium foil cling film: Through unique antibacterial technology and light-tight design, it effectively isolates air and prevents oxidation. Its preservation effect is significantly better than traditional products. Experimental data shows that aluminum-titanium foil cling film has excellent performance in terms of antibacterial property, light transmission and preservation effect.

5. Preservative covers and protective sleeves are not IQ taxes, but the effects of different products vary greatly. Among them, the effect of aluminum-titanium foil plastic wrap film with antibacterial and air isolation functions is significantly better than that of ordinary products. Ordinary plastic wrap films and plastic bags have limited effect. Ordinary plastic wrap films and plastic bags are widely used on the market, but actual tests show that they can not extend the preservation time for a long time.

The difference between antibacterial and non-antibacterial plastic wrap

1. Antibacterial plastic wrap can inhibit bacterial reproduction and is suitable for storing cooked food and meat.Miaojie plastic wrap pc and antibacterial one are easy to use; Non-antibacterial products are only physically isolated and suitable for short-term storage of dry goods. Differences in core ingredients Antibacterial cling film adds antibacterial ingredients such as silver ions, chlorine dioxide or plant extracts, which can destroy bacterial cell membranes or interfere with their metabolism, making the surface of food less likely to become sticky and smelly. Most non-antibacterial materials are PE, PVC or PVDC, which only isolate air and moistureMiaojie plastic wrap pc and antibacterial one are easy to userole.

2. The main differences between antibacterial and non-antibacterial plastic wrap are reflected in aspects such as materials and compositions, preservation effect, safety and application prospects. Materials and ingredients: Non-antibacterial plastic wrap is mainly made of traditional plastic materials such as polyethylene (PE) and polyvinyl chloride (PVC), which do not have antibacterial properties themselves.

3. Although the cost of antibacterial plastic wrap is high and its antibacterial effect on fruits and vegetables themselves is not obvious, it has been used at present. Adsorptive plastic wrap: Adsorptive plastic wrap has the effect of adsorbing and decomposing ethylene, ethanol, acetaldehyde and other gases that are unfavorable for the storage of fruits and vegetables, and also has a certain bactericidal effect.

4. However, this membrane is not an iron wall, and it cannot completely prevent the penetration and growth of all microorganisms. Some products such as Le Film Pack add antibacterial factors to inhibit bacteria by destroying the structure of microbial cells. Its antibacterial rate is claimed to reach 999%. But this is mainly aimed at the surface of the film itself, and the effect will be greatly reduced for bacteria that have been attached to the food or if the seal is not tight.

5. The principle of bacterial isolation of plastic wrap. Plastic wrap mainly relies on physical barriers to reduce bacterial contact, and the bacterial isolation effect is determined by the material and pore size. Common PE plastic wrap has large pores and has limited barrier to some small bacteria such as Escherichia coli; PVDC or plastic wrap containing antibacterial ingredients of special materials has small pores and strong bacterial isolation ability, but it cannot completely stop all microorganisms.
