Benefits of technology

The present invention provides a set of pre-padded bags and a process for making them that can reduce printing cycles and make more bags per extrusion die. The bags have a lengthwise free shrink, which prevents distortion of flexible products packaged in the bag. The bags can be connected to each other and separated from one another, making it easier to seal them. The bags can also be made with greater free shrink in the transverse direction (perpendicular to the film) to prevent distortion of the packaged products. The process for making the bags can involve using a chain of continuous polymer film webs or a single wide lay-flat film with absorbent pads placed on it. The bags can be made with longitudinal seals and transverse seals, and they can be perforated longitudinally and sealed together. The resulting bags have a unique design that allows for easy separation from one another.

Problems solved by technology

A problem with this type of packaging is that the poultry or meat contains blood and other fluids that flow out of the meat after it has been packaged.
The manual labor associated with placing the absorbent pads in the bags prior to product packaging adds to the cost and time associated with this operation.

Embodiment Construction

[0035] The present inventions now will be described more fully hereinafter with reference to the accompanying drawings, in which some but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

[0036] As used herein, the term “bag” is inclusive of L-seal bags, side-seal bags, backseamed bags, and pouches (i.e., “U-sealed” bags). An L-seal bag has an open top, a bottom seal, one side seal along a first side edge, and a seamless (i.e., folded, unsealed) second side edge. A side-seal bag has an open top and a seamless bottom edge, with each of its two side edges having a seal therealong. Although seals along the side and / or bottom edges can be at the very edge itself, (i.e., seals of a type commonly re...

Abstract

Pre-padded bags are produced from polymeric film material having a machine direction and a transverse direction, for packaging products such as fresh meats and poultry. A set of pre-padded end-seal bags comprises a first bag and a second bag, each bag comprising a first film portion and an underlying second film portion, the first and second film portions being sealed together with a transversely extending seal to form an end seal of each bag, the first and second film portions being sealed together with a longitudinal seal along the machine direction to form a side seal of each bag, the first bag being connected to the second bag in an area between the side seals of the bags, and each bag containing a fluid-absorbent pad.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to bags formed from polymeric film and containing fluid-absorbent pads for absorbing fluids. [0002] Poultry and meat are frequently sold in transparent plastic bags. A problem with this type of packaging is that the poultry or meat contains blood and other fluids that flow out of the meat after it has been packaged. The blood and other fluids accumulate in the package, detracting from its appearance. In addition, the blood and fluid sometimes leak from the package while the consumer is transporting it home from the market. To counter this problem, food bag manufacturers often insert an absorbent pad into the bag prior to packaging the food product. The pad absorbs the exuded blood and fluid and thereby enhances the appearance of the packaged product. In many cases, the absorbent pads are manually inserted into the bags. The manual labor associated with placing the absorbent pads in the bags prior to product packaging a...
