  • Publication number: 20240130901
    Abstract: A feminine hygiene article comprising a film having at least a first layer and an optional second layer, the first layer comprising at least 25 wt. %, based on the total weight of the first layer, of an ethylene acrylate copolymer and less than 75 wt. %, based on the total weight of the first layer, of a polyolefin is disclosed. The first layer may have a gloss measured by ASTM D2457 at 45° C. below 30% and a drapeability measured according to WSP 90.3 less than or equal to 10.0 gf in both the machine or cross direction. The ethylene acrylate copolymer may contain from 16-35 wt. %, based on the total weight of the ethylene acrylate copolymer, acrylate. A feminine hygiene article comprising a soft film of non plastic appearance but with high tensile strength, low elongation along with high tear and puncture resistance, and high modulus can thus be obtained.

  • Publication number: 20140251858
    Abstract: The invention relates to packaging comprising a breathable valve, intended to extend the green life of perishable products. The packaging comprises a flexible container (1) and a breathable valve assembly (2) that can be used to control the concentration of oxygen, carbon dioxide, water vapor and ethylene in the atmosphere inside the container, such as to maintain a desired value depending on the weight and the respiration rate of the product. The breathable valve assembly (2) comprises a ring (3) and a breathable lid (4) assembled in order to close the flexible container (1). The packaging is advantageous over the prior art in that it can be assembled without using any heat-sealing technique and in that it can extend the green life of perishable products, such as fruits and vegetables.
