Plastic film bag assembly and process of filling

Abstract

A plastic film bag assembly includes a bag having front and back walls joined together and defining an opening leading to a cavity. A header portion extends from the back wall for supporting the bag on a structure. A severance line extends across the header and includes tear sections extending inwardly from each of the header side edges. The severance line also includes support sections adjacent and inwardly of the tear sections. The support sections have a strength per unit length of severance line which is greater than the tear sections strength per unit length of severance line whereby, when severing the bag away from the header, a greater force is required for severing along the severance line support sections than the force required for severing along the tear sections. In use, the bag front wall lip is grasped and pulled away from the header for separating complementary profiles and opening the bag. The header tear sections are severed until reaching the support sections. The bag is retained open by continued pulling on the lip with a force insufficient for severing the support sections. Product is then placed in the bag and the lip is pulled with a sufficiently greater force for severing along the severance line support sections thereby severing the bag away from the header. For use in temporarily storing produce, the bags include a gusset for expansion and holes through the bag front and back walls for allowing air to enter the bag cavity.
