A bag with flexible sidewalls defining an interior volume is provided with leak resistant features that function to absorb and retain liquids. These features include an absorbent-adhesive mixture that may be made from an adhesive and absorbent agents such as a super absorbent polymer. The absorbent-adhesive mixture can be applied on an inner surface of the flexible sidewalls in a location where it is likely to encounter liquids. The leak resistant features can also include a substrate that may be made from a non-woven material that is also applied to the inner surface of the sidewall and can be bonded to the sidewall by the absorbent-adhesive. In various embodiments, the bag can also include odor neutralizing features and/or configured with stretchable sidewalls.

A thermoplastic bag may include a sidewall that may have a plurality of first and second ribs formed therein. The first ribs may be longer in length but shorter in height than the second ribs. The second ribs may be arranged in discrete networks that appear superimposed over the first ribs. The second ribs may normally remain in a bent-over configuration. When a force is applied, the second ribs may expand the area of the sidewall so that the bag may easily accommodate large objects. To produce the bag, a thermoplastic web may be directed between opposing first and second rollers. One of the rollers may include ridges that may have first and second segments of differing heights that correspond to the differing heights of the first and second ribs. The formation of the first ribs may increase the width of the web.

The bag for receiving refuse may include a bag body, the bag body including an inside surface, an outside surface, and a rim defining a mouth. The bag may also include a first strip of material disposed on the inside surface of the bag body proximate the rim. The strip may include an inside surface, an outside surface that faces the inside surface of the body, a top edge, and a bottom edge. The bag may also include a front wall, a back wall, and a hem, the hem including a drawstring. The strip may include a printed design. The design could be letters, numbers, pictures, writing, or any other design. When the bag is inserted into a trash receptacle such that the rim of the bag is folded over the rim of the receptacle, the printed design is visible from outside the receptacle.

摘要:
Apparatus and methods for creating multi-layered lightly-laminated provide films with increased or maintained strength. An increased level of strength is achieved by bonding adjacent layers of the multi-layer film together in a manner that the bond strength of the laminated layers is less than a strength of a weakest tear resistance of the individual first and second film layers. The inventors have surprisingly found that such a configuration of light bonding provides increased and unexpected strength properties to the multi-layer film as compared to a monolayer film of equal thickness or a multi-layer film in which the plurality of layers are tightly bonded together.

Apparatus for inserting a folded film into another folded film include combining the films without unfolding or folding either of the folded films. In particular, one or more implementations include a spreader bar configured to separate layers of a first folded film. Additionally, the apparatus can include one or more orientation rollers configured to direct a second film between the separated layers of the first folded film. Furthermore, the apparatus can include a direction change bar configured to change the direction a travel of the second film while the second film is positioned between the layers of the first folded film.
摘要:
Methods for inserting a folded film into another folded film include combining the films without unfolding or folding either of the folded films. In particular, one or more implementations of a method of combining folded films involves directing a first folded film in a first direction and separating first and second halves of the first folded film. The method also involves directing a second folded film in a second direction generally perpendicular to the first direction. Additionally, the method involves inserting the second folded film between the first and second halves of the first folded film. Furthermore, the method involves redirecting the second folded film into the first direction while between the first and second halves of the first folded film.

摘要:
A thermoplastic bag suitable for use as a liner for a garbage canister or trash receptacle may be made from a multi-layered thermoplastic web material. The multi-layer web material may include a first layer and a second layer adjacent to the first layer. Under typical conditions, the layers may tend to block or adhere together to remain in their adjacent position. However, the layers may delaminate and separate from each other when sufficient forces are applied. Delamination of the layers allows the layers to move with respect to each other when the force is applied. The delaminating of the layers absorbs energy which may increase tear and puncture resistance.
