Abstract
Abstract A packing assembly including a plurality of single packings each containing one or more articles and being surrounded by a plastic foil. The assembly is surrounded wholly or partly by two layers of plastic foil which are shrunk by heat. The invention also relates to a method of manufacturing a packing assembly of said type, in which a stack of single packings is surrounded by two plastic foils which are subsequently shrunk by heat.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
A method of wrapping at least two items, comprising the steps of first enclosing at least one of the items at least partly in an inner plastic foil, subsequently placing the enclosed items adjacent one another, thereby forming a group of items, then enclosing the group of items at least partly in an outer shrinking foil, disposing an intermediate heat protecting foil between the outer shrinking foil enclosing the group of items, and the inner plastic foil enclosing the items, thereby forming a screen, constituted by the intermediate foil, against excessive heat passage and for preventing the shrinking and the plastic foils from sticking together in the subsequent step, and subjecting the outer shrinking foil to heat shrinking.
Claim 2
Independent Claim
118 words
A method of wrapping at least two items, comprising the steps of first enclosing at least one of the items at least partly in an inner plastic foil, subsequently placing the enclosed items adjacent one another, thereby forming a group of items, then enclosing the group of items at least partly in an outer shrinking foil, disposing an intermediate heat protecting foil between the outer shrinking foil enclosing the group of items, and the inner plastic foil enclosing the items, thereby forming a screen, constituted by the intermediate foil, against excessive heat passage and for preventing the shrinking and the plastic foils from sticking together in the subsequent step, and subjecting the outer shrinking foil to heat shrinking.
Claim 3
Dependent Claim
55 words
The wrapping method as defined in claim 1, further comprising the steps of forming a double-walled bag tube of a plastic foil, by laying two plastic foil webs together, subsequently converting the bag tube into double-walled bags, placing the latter as a hood over the group of items, and subjecting the bags to heat shrinking.
Claim 4
Dependent Claim
50 words
The wrapping method as defined in claim 1, further comprising the step of placing a two-layer foil on the group of items, then wrapping the foil aroUnd the group, and subsequently welding the foil in the sides and at the top, thereby forming a hood for the group of items.
Claim 5
Dependent Claim
85 words
A packing assembly including at least two adjacently placed items, at least one of the items being at least partly enclosed in an inner plastic foil, the packing assembly being at least partly enclosed in an outer plastic shrinking foil, and an intermediate heat protecting foil arranged between said outer shrinking foil enclosing the packing assembly and said inner plastic foil enclosing the items, said intermediate foil constituting a screen against excessive heat passage and preventing said shrinking and said plastic foils from sticking together.
Claim 6
Dependent Claim
85 words
A packing assembly including at least two adjacently placed items, at least one of the items being at least partly enclosed in an inner plastic foil, the packing assembly being at least partly enclosed in an outer plastic shrinking foil, and an intermediate heat protecting foil arranged between said outer shrinking foil enclosing the packing assembly and said inner plastic foil enclosing the items, said intermediate foil constituting a screen against excessive heat passage and preventing said shrinking and said plastic foils from sticking together.
Claim 7
Dependent Claim
20 words
The packing assembly as defined in claim 4, wherein said inner plastic foil is thinner than said outer shrinking foil.
