Definitions

  • This invention relates to flexible polymeric films useful in the modified atmosphere packaging of fresh produce such as fresh fruits, vegetables and flowers.
  • the invention includes polymeric films in the form of a suitable package that can control the atmosphere surrounding fresh produce in such a way that the post-harvest life of the produce is extended.
  • the films of the invention contain a glycerolate.
  • the additives used are one or more metal glycerolates, preferably zinc glycerolate.
  • the film may be any suitable flexible polymeric film, for example polyethylene, polypropylene, polyvinyl chloride and other well-known films suitable for packaging, and preferably contain fillers, for example silica, alumina, magnesium oxide and/or pumice.
  • the glycerolate may be present in the film in an amount from 0.025 to 0.4% by weight.
  • the glycerolate is incorporated into films which also contain one or more of the agents disclosed in our above mentioned Australian application 81642/91.
  • the metal glycerolate in combination with the filling materials has an effect on voiding and pore formation of the microporous polymer film.
  • a masterbatch was prepared with low density polyethylene in which pumice and zinc glycerolate were added so that the loadings were 20% and 1% respectively. Before extrusion the masterbatch was then combined with linear low density polyethylene so that the final composition of the blown film contained about 4% pumice and .2% zinc glycerolate.
  • Example 2 In a similar manner to Example 1, a film was prepared containing 0.2% sodium permanganate, 0.1% glycerolate and 2% pumice.
