Abstract: Thermoplastic films and bags include gradient patterns of post-formation deformations. The gradient patterns of post-formation deformations can provide a connotation of strength. Additionally, the gradient pattern of post-formation deformations can provide different areas of the films or bags with different physical characteristics such as tear resistance, puncture resistance, elasticity, etc.

Abstract: Thermoplastic bags include laminates with bonded protrusions. More specifically, one or more implementations include a first thermoplastic film with a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the first thermoplastic film and second thermoplastic film bonded to the protrusions (e.g., raised rib-like elements or troughs between the raised rib-like elements) of the first thermoplastic film. By bonding a second thermoplastic film to the protrusions of the first thermoplastic film, the resulting laminate has an increased effective gauge or loft. In one or more implementations the second thermoplastic film is a flat film. In alternative implementations, the second thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the second thermoplastic film and protrusions of the first thermoplastic film are bonded to protrusions of the second thermoplastic film.

Abstract: One or more implementations of a multi-layered bag with reinforced seals include an outer layer or bag and an inner layer or bag positioned within the outer layer or bag. The multi-layered bag further includes a draw tape positioned near the opening of the multi-layered bag. The draw tape can allow a user to at least partially close the multi-layered bag by drawing the layers of the bag together. The multi-layered bag further includes one or more tape seals that bond the draw tape to layers of the bag. The tape seals can be reinforced and include at least seven plies bonded together. One or more implementations further include methods of forming multi-layered bags with reinforced seals.

Abstract: 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.
