Abstract
The invention discloses an anti-fogging preservative film, which can be in a single-layer structure and is mixed by the following ingredients in percentage by weight: 0.2-3% of anti-fogging agent, 42-99.6% of LLDPE (Linear low density polyethylene), 0-50% of MLLDPE (Metallocene linear low density polyethylene) and 0.2-5% of tackifier. The anti-fogging preservative film also can be in an A/B type double-layer structure and is composed of 10% of layer A and 90% of layer B in percentage by weight, or is composed of 20% of layer A and 80% of layer B, or is composed of 30% of layer A and 70% of layer B. The anti-fogging preservative film also can be in an A/B/C three-layer structure and is composed of 10% of layer A, 80% of layer B and 10% of layer C in parentage by weight, or is composed of 20% of layer A, 60% of layer B and 20% of layer C or is composed of 30% of layer A, 40% of layer B and 30% of layer C. No matter the anti-fogging preservative film is in the single-layer structure, the double-layer structure and the three-layer coextrusion structure, the preservative film has an anti-fogging effect because the antifogging agent is added into the raw material so as to avoid generating fog on the surface of the preservative film, which is convenient for consumers to clearly see the preserved commodity.
Description
Technical field
