Description

PACKAGING BAG AND METHOD OF MAKING AND USING THE SAME

TECHNICAL FIELD

The present disclosure relates to a packaging bag, and more particularly to, a packaging bag with a transparent body and a tearable or peelable header.

BACKGROUND ART

Packaging bags are used for packaging many products shipped and sold. In some cases, packaging bags may be used to ship sensitive products that are used in clean room or sterilized conditions, such as medical, biological, or pharmaceutical products. In some cases, these packaging bags must be sterilized themselves to avoid contamination of the packaging bag surroundings when and where the product is needed. In certain cases, vaporized hydrogen peroxide (VHP) sterilization is required such that VHP resistant packaging is needed to protect these sensitive products. However, these VHP packaging bags may not be transparent and may be difficult to open without the use of tools (including sharps). This may prove burdensome in sterilized conditions. Therefore, improvements in packaging bags are needed, particularly in enabling packaging bags to achieve optimal VHP resistance while allowing improved ease of use.

In embodiment, at least one of the packaging bag, the first film composition, or the second film composition may have further desirable physical and mechanical properties. For instance, at least one of the packaging bag, the first film composition, or the second film composition may appear transparent or at least translucent. For instance, at least one of the packaging bag, the first film composition, or the second film composition may have a light transmission greater than about 2%, or greater than about 5% in the visible light wavelength range. In particular, the resulting articles have desirable clarity or translucency. In addition, at least one of the packaging bag, the first film composition, or the second film composition have advantageous physical properties, such as a balance of any one or more of the properties of hardness, flexibility, surface lubricity, tensile strength, elongation, Shore A hardness, gamma resistance, weld strength, and seal integrity to an optimum level.

In an embodiment, at least one of the packaging bag, the first film composition, or the second film composition may have desirable heat stability properties. Applications for the polymer or polymeric blend are numerous. In particular, the polymer or polymeric blend is non-toxic, making the material useful for any application where no toxicity is desired. For example, the polymer or polymeric blend may be substantially free of plasticizers or other low-molecular weight extenders that can be leached into the fluids it transfers. “Substantially free” as used herein refers to a polymeric mixture having a total organic content (TOC) (measured in accordance to ISO 15705 and EPA 410.4) of less than about 100 ppm. Further, the polymer or polymeric blend has biocompatibility and animal derived component-free formulation ingredients. For instance, the polymeric mixture has potential for FDA, USP,

EP, ISO, and other regulatory approvals. In an exemplary embodiment, the polymer or polymeric blend may be used in applications such as industrial, medical, health care, biopharmaceutical, pharmaceutical, drinking water, food & beverage, laboratory, dairy, and the like. In an embodiment, the polymeric mixture may be used in applications where low temperature resistance is desired. In an embodiment, the polymer or polymeric blend may also be safely disposed as it generates substantially no toxic gases when incinerated and leaches no plasticizers into the environment if land filled.

In particular embodiments, packaging bag may be torn or peeled to form an “open position” from a “closed position” In particular embodiments, packaging bag 200 may be tearable or peelable to form an open position upon application of force of no greater than about 10 lbf, no greater than about 5 lbf, no greater than about 2.5 lbf, no greater than about 2 lbf, or no greater than about 1 lbf. The bag may be torn or peeled at the interface between the header and the transparent body, at a location along the header only, or at a location along the transparent body only.

Experiments will be conducted regarding the materials for best peel ability between the header and the transparent body. Materials of the header and the transparent body will be varied through these experiments. A positive performance for the best peel ability between the header and the transparent body may be based on the variations of sizing of the packaging bag and materials of the header and transparent body, some potentially demonstrating criticality. The peel ability between the header and the transparent body may be measured by application of force upon at least one of the header or the transparent body of the packaging bag.

A method may be used for forming a packaging bag according to a number of embodiments. The method may include a first step including providing a transparent body comprising a first film composition. The method may include a second step of providing a tearable or peelable header comprising a second film composition. The method may include a third step of bonding the second film composition to the first film composition to form a closed packaging bag. The method may include a fourth step of sterilizing the packaging bag such that the packaging bag is VHP resistant such that hydrogen peroxide concentration on an interior of the package is less than 1 ppm. Optionally, the method may include a step of disposing a product between the transparent body and the tearable or peelable header before or after bonding the second film composition to the first film composition to form a closed packaging bag.

Use of the packaging bag may provide increased benefits in several applications in fields such as, but not limited to, industrial, medical, health care, biopharmaceutical, pharmaceutical, drinking water, food & beverage, laboratory, dairy, or other types of applications. Notably, the use of the packaging bag or packaging bag and container system may provide a sealing mechanism for housing a product meant for sterilization, such as a medical device, pharmaceutical product, or biological product used in a surgical procedure. Further, the use of the use of packaging bag may provide a VHP resistant container with an ease of transition from a closed position to an open position to remove the product without the use of any tools or sharps. This may provide optimal sealing engagement while allowing improved ease of use in difficult environments, such as operating rooms, hospitals, or pharmacies.

Claims

WHAT IS CLAIMED:

1. A packaging bag, comprising: a transparent body having a first film composition; and a tearable or peelable header comprising a second film composition, wherein the first film composition and the second film composition are different, wherein a component of the first film composition is bonded to the second film composition.

2. A packaging assembly comprising: a product; and a packaging bag enclosing the product to provide a sterilize-able packaging assembly, wherein the packing bag comprises: a transparent body having a first film composition; and a tearable or peelable header comprising a second film composition, wherein the first film composition and the second film composition are different, wherein a component of the first film composition is bonded to the second film composition, wherein the packaging bag is VHP resistant such that hydrogen peroxide concentration on an interior of the package is less than 1 ppm.

3. A method for forming a packaging bag, comprising: providing a transparent body comprising a first film composition; providing a tearable or peelable header comprising a second film composition; bonding the second film composition to the first film composition to form a closed packaging bag; and sterilizing the packaging bag such that the packaging bag is VHP resistant such that hydrogen peroxide concentration on an interior of the package is less than 1 ppm.

4. The packaging bag, packaging assembly, or method of any of the preceding claims, wherein the first film composition comprises polyethylene.

5. The packaging bag, packaging assembly, or method of any of the preceding claims, wherein the second film composition comprises polyethylene.
