Grease-resistant bag having adhesive closure, adhesive closure for bag, and related methods

Abstract

An embodiment of a bag includes a bag body having opposing bag ends and an inner face of an outer ply abuttingly adhered to an outer face of an inner ply with an adhesive. The bag can also include the outer ply having an inner face of a grease-resistant film abuttingly adhered to an outer face of a paper layer with an adhesive. The bag can further include the inner ply having a film of one or more layers having a grease-resistant material adapted to advantageously closingly seal at least one of the bag ends. An adhesive advantageously adheres a portion of a bag end to another portion of the same bag end to closingly seal the bag end. Embodiments of other bags, bag closures, and methods of assembly, positioning, using, and constructing a bag are also provided.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to the bags or packaging industry, and more particularly, to grease-resistant bags having an adhesive closure and related methods. [0003] 2. Description of the Related Art [0004] Consumer packaging is important in today's marketplace. Not only do the products within the packaging have to be fresh, but the outside portions of the packaging must be aesthetically appealing. Traditionally, the focus has been to either sacrifice external appearance for internal protection, or sacrifice internal protection for external appearance, but seldom are the concerns with both external appearance and internal protection addressed with a single bag. [0005] Furthermore, foods such as pet foods can exhibit an increased grease or fat component. The grease component of these foods in the past tended to penetrate the layers of the bag or gradually led to deterioration of the bag over time. The inc...

Benefits of technology

[0015] A further advantage of the present invention is the environmentally friendly composition of the structure of the present invention by producing bags 18 that are less toxic and increasingly biodegradable, while maintaining inexpensive costs relative to other types of potentially environmentally friendly bags 18. Further, the bag 15 can advantageously be manufactured on existing equipment previously utilized for manufacturing bags 18, so there is no necessity to invest in new and expensive bag 15 manufacturing equipment.

[0016] Embodiments of the invention can have many alternative bag styles in addition to the embodiments described, such as for example bag styles of a gusseted pinch-bottom bag, a pinch-bottom bag not gusseted, other various pinch-bottom styles of bags, heat-sealable bags of various constructs, and block-bottom bags of various constructs. Such features are interchangeable, as understood by those skilled in the art, and are determined by the requirements of the marketplace. Regardless of what type of bag is to be constructed, another advantage of embodiments of the present invention is that each can be run on conventional bag producing machines, as understood by those skilled in the art. Embodiments of the bags manufactured in this way using the described construction and materials also offers the advantage of allowing the bag to be made containing consumer features such as easy-carry handles, reclosable zippers, and easy-to-open features, and cost-effective measures.

Problems solved by technology

The grease component of these foods in the past tended to penetrate the layers of the bag or gradually led to deterioration of the bag over time.

Problems have also persisted regarding adequate sealing measures for the bag ends of the bags.
