Abstract

A packaging material comprises a bubble sheet (1), bonded to a layer of protective material (2). The protective material (2) may be a low density polyethylene film, a high density polyethylene film, a polypropylene film or extended polyethylene foam. The protective material (2) may be heat-sealed under pressure to the bubble sheet (1) and a liquid film of LDPE (3) may be coated on the at least one surface of the bubble sheet (1) before heat-sealing in order to strengthen the seal. The protective material (2) may have printed matter thereon. The packaging material may then be folded and sealed along its sides to form, for example, a bag or container. <IMAGE>

Description

"Lamination of a Bubble Sheet" The present invention relates to the process of laminating a bubble sheet, and more particularly, to the process of laminating a bubble sheet with a layer of protective material for use as a packaging material.
Bubble sheets are often used to package and protect fragile objects and to help prevent breakage of objects due to, for example, collision with other objects during transportation. The bubble sheet acts as a shock absorber, but is of little use in protecting objects against scratches, dust, moisture and/or chemical attack. Scratch proof, dust proof, acid proof, alkaline proof and waterproof films or foams have also been used to package fragile objects, but only as a layer of packaging material separate to and sometimes in addition to the abovementioned bubble sheets. However, a disadvantage of using such protective films or foams in addition to the bubble sheets is that moisture and/or air may become trapped between the two layers.
In order to overcome the afore-mentioned problems, the present invention involves a new concept and technique of bonding two different types of material together to provide a single packaging material, comprising a bubble sheet and a scratch proof, dust proof, acid proof, alkaline proof and waterproof protective layer such as a film or foam. The packaging material of the present invention thus has the protective qualities of both bubble sheets and protective films and foams. The combined layers offer increased elasticity and strength as compared with use of the two layers separately and, because no moisture can be trapped between the two bonded layers of the packaging material of the present invention, greater protection is afforded against moisture. In addition, use of the combined layers provides increased protection against acidic or alkaline attack.Air is eliminated between the two layers of the packaging material of the present invention, which therefore reduces exposure to air as compared with use of the two layers separately and, consequently, exposure to chemical reaction with the air is also reduced.
Other advantages of using the packaging material of the present invention include time saved in using a single sheet of packaging material rather than two (or more), space saved during transportation (due to elimination of the air space between the two or more layers) and the resulting reduction in costs of packaging and/or transportation.
Another advantage of the present invention is that the protective layer is suitable for printing any desired matter thereon and that the printed side of the protective layer may be securely positioned between the protective layer and the bubble sheet, thereby preventing damage of the printed matter as a result of movement or friction.
Furthermore, the packaging material of the present invention may be recyclable, reusable and naturally decomposable.
The packaging material of the present invention may be used to package, for example, all types of glasr containers, porcelain, silver ware, photo-frames, fragile furniture and electronics products such as cameras, television sets, hi-fi and audio equipment, computers and telephones etc.
According to the present invention, there is provided a process of laminating a bubble sheet, which process comprises bonding a layer of protective material to at least one surface of the bubble sheet. This provides an air-tight, water-tight seal between the bubble sheet and the layer of protective material.
Preferably, the layer of protective material is heat-sealed under pressure to the at least one surface of the bubble sheet.
Preferably, the at least one surface of the bubble sheet is coated with a bonding agent before heat sealing the layer of protective material to the bubble sheet, and preferably the bonding agent comprises a film of liquid low-density polyethylene. The bonding agent may form a seal upon drying or curing. This provides a tighter seal between the bubble sheet and the layer of protective material.
According to the present invention, there is further provided a packaging material which comprises a bubble sheet bonded to a layer of protective material.
The bubble sheet acts as a shock absorber.
Preferably, the bubble sheet comprises low density polyethylene.
The layer of protective material preferably comprises a low density polyethylene film, a high density polyethylene film, a polypropylene film or extended polyethylene foam. The protective layer provides protection against acid, alkaline or other chemical attack, scratches, dust,and water.
Preferably the layer of protective material has printed matter thereon.
Preferably the printed matter is on the inner surface of the layer of protective material positioned between the layer of protective material and the bubble sheet. This prevents damage to the printed matter, as a result of movement or friction.
The laminated bubble sheet may be heat sealed under pressure along at least one of its sides to form a bag or container.
In order to illustrate the features and advantages of the present invention, the present invention will be further described, by way of example only, and with reference to the accompanying drawings, in which: Figure 1 shows a diagrammatic cross-sectional view of a sheet of non-printed packaging material in accordance with a first embodiment of the present invention.
Figure 2 shows a diagrammatic cross-sectional view of a sheet of printed packaging material in accordance with a second embodiment of the present invention.
Figure 3 shows a diagrammatic cross-sectional view of a sheet of printed packaging material in accordance with a third embodiment of the present invention.
With reference to Figure 1, an embodiment of the packaging material according to the present invention comprises a low density polyethylene (LDPE) bubble sheet 1 laminated with a layer of protective material 2. The protective material 2 may be a low density polyethylene (LDPE) film, a high density polyethylene (HDPE) film, a polypropylene (PP) film or extended polyethylene (EPE) foam.
LDPE bubble sheets, LDPE, HDPE and PP films, EPE foam and their manufacture are well known in the art, and so a detailed description thereof is omitted.
During manufacture of the packaging material shown in Figure 1, an LDPE bubble sheet 1 is coated with a liquid film of LDPE 3 and is then laminated with a layer of one of the above-mentioned protective materials 2 using a well known method of heat sealing under pressure. Heat-sealing provides an air-tight, water-tight seal between the LDPE bubble sheet 1 and the layer of protective material 2, while the liquid LDPE film 3 dries to bond the two layers together and serves to increase the strength of the airtight, water-tight seal.
A layer of protective material 2 may be laminated on either or both faces of the LDPE bubble sheet 1. The resulting packaging material may then be folded and heat sealed under pressure along at least one of its sides to produce, for example, a bag or container.
With reference to the second embodiment of the present invention illustrated in Figure 2, the protective layer 2 has previously been printed, for example, with a desired pattern, words, and/or logo 4.
In Figure 2, the layer of protective material 2 has been laminated on the LDPE bubble sheet 1 with the printed side 4 outwards, ie., with the printed side 4 on the outer surface of the packaging material.
In the third embodiment, shown in Figure 3, the layer of protective material 2 also has printed matter 4 thereon. However, in this example, the layer of protective material 2 is laminated on the LDPE bubble sheet 1 with the printed side 4 inwards ie. with the printed matter 4 positioned between the layer of protective material 2 and the LDPE bubble sheet 1. In such cases it is preferred that the layer of protective material 2 be translucent or transparent.
