core tip: summer is coming, and it's time to choose the brand of fresh-keeping box. In summer, food is easy to deteriorate, and it's too wasteful to throw away unfinished food. Choosing the right fresh-keeping method for food is a matter of great concern to every family, Food and health are closely related, and the choice of fresh-keeping box brands has been valued by more and more families, for example; We often use two kinds of fresh-keeping boxes, glass fresh-keeping box and plastic fresh-keeping box, which kind of fresh-keeping effect is better? Which kind of contact with food is the most healthy and harmless? Now let stntus tritantm vacuum preservation tell you

[China Packaging News] summer is coming, and it's time to choose the brand of fresh-keeping box. In summer, food is easy to deteriorate, and it's too wasteful to throw away the unfinished food. Choosing the right fresh-keeping method for food is a matter of great concern to every family. Food is closely related to health, and the choice of fresh-keeping box brand has been valued by more and more families, for example; We often use two kinds of fresh-keeping boxes, glass fresh-keeping box and plastic fresh-keeping box, which kind of fresh-keeping effect is better? Which kind of contact with food is the most healthy and harmless? Now let stntus tritantm vacuum preservation tell you

comparison of various kinds of fresh-keeping boxes:

1. Glass fresh-keeping box

has tempered glass fresh-keeping box and heat-resistant glass fresh-keeping box

advantages: safe material, high transparency, and heat-resistant glass can withstand high temperature

disadvantages: tempered glass will burst at high temperature, and the product is bulky and fragile, which is not suitable for carrying, and the tightness is not good

2. Plastic PP fresh-keeping box

non toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than low-pressure polyethylene, and can be used at about 100 degrees It has good electrical performance and high-frequency insulation, and is not affected by humidity. The density is 0 91. High heat resistance, good toughness and chemical corrosion resistance. Food plastic products are the most commonly used

disadvantages: brittle at low temperature, not wear-resistant, easy to aging

3. Plastic PET material

milky white or light yellow, highly crystalline polymer, with smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. It is heat-resistant to 70 ℃. It is only suitable for warm or frozen drinks. It is easy to deform when it is filled with high-temperature liquid or heated

such as mineral water bottles, so never take mineral water bottles to fill hot water

4. Plastic PC material

an amorphous thermoplastic resin with excellent comprehensive performance, which has excellent electrical insulation, extensibility, dimensional stability, chemical corrosion resistance and high strength; It also has the advantages of self extinguishing, flame retardant, non-toxic and colorable

disadvantages: the disadvantages are that compared with metal, the hardness is insufficient, and the appearance is easy to scratch. PC glue releases bisphenol a when it meets heat. Pay special attention when using this plastic container. Many water cups and milk bottles use this material

5. Tritantm fresh-keeping box

1) does not contain BPA, which is the safest material for food contact: no? BPA ingredients, which will not release BPA during use, meet environmental requirements and FDA certification

2) high molecular density, antioxidant, long-term storage of food without odor residue, no pigmentation: as clear and transparent as glass, light transmittance of 90%, haze of 1%, with crystal luster. It can resist the corrosion of detergents, detergents, hydrocarbon solvents, oils, perfume, etc; It can resist hydrolysis in hot and humid environment

3) high impact strength, which can be used for high vacuum storage and prevent atmospheric pressure extrusion deformation: second, measured according to ISO international standards, there is no notch impact and fracture, and the notch impact strength is close to 1000j/m, which is higher than PC material and more than 300 times that of glass

4) high temperature resistance, can be used for direct heating in microwave oven: no deformation at 200 ℃ and no odor release

5) low stress, strong and durable, no damage after falling: after injection molding, the residual stress of the product is smaller than that of PC, and there is no need for subsequent annealing. There are few opportunities for products to crack due to residual stress during use. Free fall from the second floor (5m high) will not cause damage and cracking when the investor meets the requirements of PE double wall corrugated pipe, winding pipe and various pipe standards

stntus (Xiantu) vacuum fresh-keeping box imported from Europe uses tritantm material, which is an essential product for European and American families. The product has been recognized by EU Member States and conforms to international standards. Stntus (Xiantu) fresh-keeping box can be vacuumized manually or with a vacuum fresh-keeping machine to start the third generation of vacuum fresh-keeping journey, and China will also enter the era of vacuum fresh-keeping

tension pressure sensors and force measuring instruments can only be measured by lever force standard machine or static weight force standard machine. Statement:
