Abstract
A flexible film and flexible food storage bag for packaging produce such as vegetables and fruits wherein the film or bag has plurality of microholes specifically designed to allow the produce to breath in a controlled rate such that localized condensation and weight loss is minimized, which in turn reduces microbial (bacteria and mold) growth and reduces produce mushiness (softness) respectively.
Claims28
Vegetable containing storage bag comprising
- (a) vegetables selected from the group consisting of low, medium or high respiring vegetables;
- and
- (b) a flexible food storage bag having the vegetables stored therein, said flexible food storage bag comprising a flexible bag having sidewalls, a bottom, side seams and a closable top, said bag being made from a thermoplastic flexible film and said bag having a plurality of microholes through the film of the bag, each of said microholes having a diameter of from about 250 microns to about 950 microns, said microholes uniformly distributed in the bag to provide a percent void area in the bag of from about 0.05 percent to about 2.75 percent, wherein the void area is defined by
- V=[(H).sup.2 x(.pi./4)xD]x 100
- wherein V=the percent void area per bag
- area;
- H=hole diameter;
- and D=hole density which is the number of holes per bag area;
- such that localized condensation in the bag is such that no matter what type of vegetables are stored in the bag -low, medium, or high respiring vegetables -the Padres number of the bag as represented in the formula
- Padres Number=Log [(C/W.sub.tl)x100
- where C is the condensation in the bag calculated in grams, and W.sub.tl is the total weight loss of the vegetable calculated in grams,
- is less than 1.74 and the weight loss of the vegetables is less than about 8 percent when stored at a temperature of about 10.degree. C. and at a relative humidity of about 30 percent for at least three days, the thickness of the bag wall being less than 5 mils.
