Description
REINFORCEMENT HANDLE FOR BAG AND METHOD OF ASSEMBLY THEREOF
FIELD OF THE INVENTION
The present invention generally relates to bag handles. More particularly, the present invention relates to a reinforcement handle for a bag and a method for assembling such a handle on a bag.
BACKGROUND OF THE INVENTION
Carrier bags for shopping have been produced from a variety of materials and in various designs, and have been in use for the past 50 to 100 years. Paper and later plastic film have been the materials of choice during the 20th century.
Because of environmental concerns, paper and plastic bags have lost some of their popularity. Re-useable shopping bags made from woven polyolefin laminated materials have gained popularity of late. These bags, mostly coming from Asia, are fabricated from Polyolefin fabrics which are further extrusion coated and/or laminated with Polyolefin film resin.
The fabrication of the finished bag and the attachment of webbing handles is carried out with lock stitch type sewing machines. Such sewing machines are designed for sewing garments made from high-count natural and synthetic materials.
The bags in questions are made from low-count polyolefin tape fibre fabrics.
Such fabrics, are the economic fabric of choice for many industrial and now consumer applications. Such fabrics, while possessing high shear strength, have a low tear strength when subjected to a extraordinary amount of seam punctures.

BACKGROUND OF THE INVENTION
Carrier bags for shopping have been produced from a variety of materials and in various designs, and have been in use for the past 50 to 100 years. Paper and later plastic film have been the materials of choice during the 20th century.

These bags, mostly coming from Asia, are fabricated from Polyolefin fabrics which are further extrusion coated and/or laminated with Polyolefin film resin.
The fabrication of the finished bag and the attachment of webbing handles is carried out with lock stitch type sewing machines. Such sewing machines are designed for sewing garments made from high-count natural and synthetic materials.
The bags in questions are made from low-count polyolefin tape fibre fabrics.
Such fabrics, are the economic fabric of choice for many industrial and now consumer applications. Such fabrics, while possessing high shear strength, have a low tear strength when subjected to a extraordinary amount of seam punctures.
The stitch rate inherent in these machines is between 2.3 to 2.75 per centimeter.
Acceptable stitch rate for the polyolefin materials is no more than 1.6 per centimeter.
This higher stitch rate results in weaker seams both in the body of the bags and the handles.
As the seams become the weakest area in the bag, the strongest bag will have no sewing seams both in the forming of the bag or the attachment of handles which could weaken the bag.
There is therefore a need for a molded plastic reinforcement handle and its attachment onto a bag. The handle is to be attached to a bag made from fabric woven from tapes of oriented woven polyolefin film, which is then coated on one of both sides with polyolefin films.
Polyolefin tape fabric and polyolefin woven webbed handles cannot be sealed in the same manner as common polyethylene or polypropylene film bags. Polyolefin films including both polyethylene and polypropylene are sealed with band sealers, impulse sealers and hot bar sealers. These sealing devices usually require heat to pass through the material to the interface to be sealed. Since damage has been observed on fabric temperatures exceeding 220 F, this type of heat sealing is not recommended nor acceptable. Other sealing methods such as hot melt or molten resin sealing tend to be less desirable because they are too complicated, specifically for the attachment of handles. Sewing web handles onto a bag are used but suffer from strength limitations as described above, and require a highly labour intensive procedure to achieve.
Consequently, there is a need for a reinforcement handle that provides improved strength properties to the bag while being less labour-intensive in its installation on the bag.
