Benefits of technology

It is a further object of the invention to provide dunnage on site by a method which can be operated easily by personnel without expertise in the production of dunnage.
It is also possible to produce the plastic film with degradable additives in order to aid in disposal.

Problems solved by technology

Applicants have discovered that it is far more difficult to produce a web of plastic bags than it is to convert a web of plastic bags to inflated dunnage.

Embodiment Construction

As shown in FIG. 1, the starting material of the process is a roll 10 of plastic bags, the roll comprising a backing sheet 14 and a facing sheet 16. The roll of bags is shown in detail in FIG. 2, each bag 12 formed from a first longitudinal seal 18, a second longitudinal seal 20 and a lateral seal 22. Edge 24 is not sealed. Outer surface 12a is slip resistant; inner surface 12b is more slippery than outer surface 12a to make the bags easier to open. The roll of bags passes between feed rolls 30 and 32, the rolls creating enough tension to cause a slight opening in edge 24. Air tube 34 blows air at slightly opened edge 24, as the bag passes the tube, causing the bag 12 to inflate. The bag then passes between seal head 36 and seal backup 38, which places a lateral seal 40 across edge 24 of the bag. The bags then pass a separating station 44 which is activated at predetermined intervals to cut across lateral seal 40 and form an individual sealed bag 12s, or a unit with multiple sealed ...

Abstract

A method for producing inflated dunnage on the site of use, comprising providing, in web form, a plurality of preformed plastic bags, each of the bags comprising two plastic sheets in facing relationship and sealed along three edges with one edge remaining open. Air is blown toward each of the open edges in sequence, causing each bag to inflate, and the open edge of each inflated bag is sealed, the bag being empty except for the air. A plurality of sealed inflated bags is separated from the web and placed in a carton to serve as dunnage. The bags have a slip resistant outer surface which causes the bags to interlock in the carton and better protect object therein from shock.

Description

BACKGROUND OF THE INVENTIONThe invention relates to a process for producing dunnage directly on the site of use, and the dunnage produced thereby.Materials with low density and high volume are commonly used as packing materials to insulate goods being shipped from shock. Among the materials used are polystyrene "peanuts", "cups" and "worms," pellets of foam rubber, foam plastics and expanded polyurethane foam. Air cushioning material is generally preferred over the above types of dunnage because it is lighter in weight, can be supplied and dispensed in a controlled manner, particularly in web or folded form, and applied to the product to be shipped in sheet form. The sheet form of material is also easier to dispose of than the individual pieces of plastic dunnage after the product is removed, and the sheet form of material can be rewound for further use or disposed of by deflation.However, air cushioning material also presents a variety of problems, as large volumes of the material ...
