One of the few downsides of flexible packaging is that there may be bulging caused by lack of support for larger bags, but this invention poses a unique solution to the problem.
This patent filing from Hill's Pet Nutrition Inc., Topeka, KS, is for a flexible packaging that uses an interior strap to connect front and back walls for support. The strap can be more than one heat-welded to opposing walls and can be in a crisscross configuration. This permits a flexpack with squared-up walls, rather than the typical rounded sides, yielding a package that can contain product in an efficient, linearly symmetrical shape without bulging. Such a pack offers prominent and desirable front-forward shelf positioning and can be stacked.
Additionally, there is an allowance for a flexible packaging container that has an easy-pour system and is also resealable using a slider or other style of reclosure. Also, heat-weldable handles can be affixed to the package for consumer convenience.
While noting the applicability of the package for a granular or dry dog or cat food, the invention explicitly states that it can contain any type of dispensable or flowable product in product netweights ranging from 3.5kg to 16kg or roughly 7.75 lb to 35.25 lb. Appropriate thermoplastic films include polyethylene and polyester.
