Gloves are the most commonly used protective tools in the laboratory besides goggles. There are many types of gloves, and different gloves have different uses.     1. Natural rubber (latex) Latex gloves, made from natural rubber, typically lack a lining and are available in both clean and sterile versions. These gloves can provide effective protection against alkalis, alcohols, and a variety of chemical dilution aqueous solutions, and can better prevent corrosion from aldehydes and ketones.   2. Polyvinyl chloride (PVC) gloves The gloves do not contain allergens, are powder-free, have low dust generation, low ion content, strong chemical corrosion resistance, can protect almost all chemical hazardous substances, and also have anti-static properties. Thickened and treated surfaces (such as fleece surfaces) can also prevent general mechanical wear, and thickened types can also prevent cold, with an operating temperature of -4℃ to 66℃. Can be used in a dust-free environment. PVC gloves grading standards: Grade A products, no holes on the surface of the gloves (PVC gloves with powder), uniform powder, no obvious powder, transparent milky white color, no obvious ink spots, no impurities, and the size and physical properties of each part meet customer requirements. Grade B products, slight stains, 3 small black spots (1mm≤diameter≤2mm), or a large number of small black spots (diameter≤1mm) (diameter>5), deformation, impurities (diameter≤1mm), slightly yellow color, serious nail marks, cracks, and the size and physical properties of each part do not meet the requirements.   3. PE gloves PE gloves are disposable gloves made of polyethylene. These gloves are waterproof, oil-proof, anti-bacterial, and resistant to acids and bases. Note: PE gloves are safe to use with food and are non-toxic. It is better to keep PVC gloves away from food, especially if it's hot.     4. Nitrile rubber gloves Nitrile rubber gloves are usually divided into disposable gloves, medium-duty unlined gloves and light-duty lined gloves. These gloves can prevent erosion by grease (including animal fat), xylene, polyethylene and aliphatic solvents; they can also prevent most pesticide formulations and are often used in the use of biological components and other chemicals. Nitrile rubber gloves do not contain protein, amino compounds and other harmful substances, and rarely cause allergies. They are silicone-free and have certain antistatic properties, which are suitable for the production needs of the electronics industry. They have low surface chemical residues, low ion content and small particle content, and are suitable for strict clean room environments.   5. Neoprene gloves Similar to the comfort of natural rubber, neoprene gloves are resistant to light, aging, flexing, acid and alkali, ozone, combustion, heat and oil.   6. Butyl rubber gloves Butyl rubber is only used as a material for medium-sized unlined gloves and can be used for operations in glove boxes, anaerobic boxes, incubators, and operating boxes; it has super durability against fluoric acid, aqua regia, nitric acid, strong acids, strong alkalis, toluene, alcohol, etc., and is a special rubber synthetic resistant liquid gloves.   7. Polyvinyl alcohol (PVA) gloves Polyvinyl alcohol (PVA) can be used as a material for medium-sized lined gloves, so this type of gloves can provide a high level of protection and corrosion resistance against a variety of organic chemicals, such as aliphatic, aromatic hydrocarbons, chlorinated solvents, fluorocarbons and most ketones (except acetone), esters and ethers.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com

The shift toward green packaging in the food industry is imperative.   Flexible packaging is becoming really important in the food industry. This product is safe for the environment and doesn’t contain any toxic materials. Unlike PVDC, it leaves no solvent residues and doesn’t release harmful gases when burned, so it’s a better choice for sustainability.   Under the same conditions, its oxygen barrier performance is 50 times higher than that of PVDC, effectively addressing many challenges in the packaging industry.   Polyvinyl alcohol (PVC Grade) coated film is a novel, eco-friendly, high-barrier packaging material that can replace PVDC in general food packaging applications while also meeting stricter environmental requirements in other packaging fields.   Differences Between PVOH High-Barrier Coated Film and K-Film     1. Structure: Self-adhesive, no primer required.        2. Performance:   Eco-friendly & Cost-Efficient: Low coating weight, no organic solvents used, no solvent emissions or residues. Superior Oxygen Barrier: Thinner coating, lower haze, higher transparency, and exceptional oxygen barrier performance. Higher Yield: It offers a bigger packaging area, about 15% more per roll than K-film of the same weight and width, which means you can pack more products. . Recyclability: The PVOH-coated film is both degradable and recyclable.   In summary, this eco-friendly PVOH (PVOH 552 & Aclotex B72) -coated film could fill a gap in the market. It can replace traditional PVDC in food packaging and meet the needs of industries focused on environmental issues. Plus, it effectively handles current sustainability challenges and provides good oxygen barriers for flexible food packaging.It's likely to take the place of a lot of metallized film packaging out there.   This new product is designed to tackle the ongoing issue of plastic waste in food packaging and support the move towards eco-friendly materials in China.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
