Acta Medical ACTAMIX4000 - 4000 ML Ethyl Vinyl Acetate (EVA) Bag, 50/CS
Ethyl Vinyl Acetate (EVA) Bag
Ethyl Vinyl Acetate (EVA) bags are constructed from a single-web, medical grade laminate of four different films, with a fluid contact surface of EVA, with two layers of low-density polyethylene (LDPE) enveloping a layer of ethyl vinyl alcohol (EVOH).
- Sterile.
- PVC, DEHP, and Latex free.
- 1000ml.
- Quick disconnect compounder connections available for all compounders.
- Unique Dual Chamber design containers available.
These bags are specifically designed to provide strong seals, extraordinary robustness, superior flex, crack and pin-hole resistance, plus desirable gas and moisture barrier performance.
What is Ethylene-vinyl acetate?
Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used. The EVA copolymer which is based on a high proportion of VA (greater than 40%) is referred to as ethylene-vinyl acetate rubber.
EVA is an elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl products in many electrical applications.
Low-density polyethylene (LDPE)
LDPE is defined by a density range of 0.9100.940 g/cm3. LDPE has a high degree of short- and long-chain branching, which means that the chains do not pack into the crystal structure as well. It has, therefore, less strong intermolecular forces as the instantaneous-dipole induced-dipole attraction is less. This results in a lower tensile strength and increased ductility. LDPE is created by free-radical polymerization. The high degree of branching with long chains gives molten LDPE unique and desirable flow properties. LDPE is used for both rigid containers and plastic film applications such as plastic bags and film wrap.
- Excellent resistance (no attack / no chemical reaction) to dilute and concentrated acids, alcohols, bases and esters.
- Good resistance (minor attack / very low chemical reactivity) to aldehydes, ketones and vegetable oils.
Storing
EVA must be stored at temperature under 40 degree celsius. The sun radiation, heat, humidity is prohibit.
