Abstract

In a process for manufacturing a coated wallcovering made of paper or fabric, a hot, transparent polyolefin film e.g. of polyethylene is laminated thereto. The film is preferably obtained hot from an extruder and laminated to the substrate by passage through the nip of a pair of rollers.

Description

SPECIFICATION Coated wallpaper The present invention relates to coated wallpaper, the term 'wallpaper' meaning in this specification wall coverings whether made of paper, fabric, or other suitable material, and not being restricted to wallpaper made of paper. More specifically, it relates to the coating of wallpaper with a film of synthetic plastics material.
Plastics coated wailpapers have previously been prepared by coating a single- or multiply wallpaper with a latex or solution of a synthetic polymer. This procedure has certain disadvantages, particularly because it is a wet process and it is necessary to allow the latex to cure or the solvent to evaporate.
It is also known to manufacture plasticscoated record sleeves by using a layer of adhesive to adhere a preformed plastics film to a record sleeve. In this instance the presence of the adhesive layer helps to give rigidity to the sleeve, a characteristic which is desirable for record sleeves but not for wallpaper. Moreover the adhesive represents extra cost, requires application and adds weight to the product.
According to the present invention, there is provided a process for manufacturing a coated wallpaper in which a hot, transparent polyolefin film is laminated to wallpaper. The hot polyolefin film has sufficient tackiness to give good adhesion to the wallpaper upon cooling, and as such no separate adhesive is required.
The polyolefin will typically be a low or high density polyethylene, and usually the polyolefin film will be one prepared by extrusion. In this latter instance the film can be fed from the extruder while still hot and applied to the wallpaper. A typical temperature for the hot polyolefin film is in the range 1 50 to 280"C.
A convenient thickness of film is from 8 to 20 microns say about 1 2 microns.
If the wallpaper has a printed pattern it may be desirable to stabilize the pattern before the polyolefin film is applied. Certain inks currently used for wallpaper tend to bleed when exposed to high temperature, but this bleeding can be prevented by heat-setting the pattern. Heat-setting involves exposure to less heat than gives bleeding of the ink but yet which is still sufficient to fuse the ink into the wallpaper.
After the optional heat-setting of the wallpaper pattern the hot plastics film is laminated thereto by melt adhesion. Lamination can be effected as a continuous process by taking hot film from an extruder, offering the film to the wallpaper and passing the pre-laminate through the nip of a pair of rollers. The resultant laminate can then be wound up.
The coated wallpaper provided by the invention is fully comparable with, if not superior to, other coated wallpapers currently available, particularly with regard to flexibility and weight, and yet has the advantage of simplicity in manufacture. The continuous process can be operated at relatively high speeds, with the wallpaper typically being advanced at a speed of 50 to 300 m/min.
The process of the present invention is illustrated by the following example.
Example Low density polyethylene was heated to 300"C in an extruder and extruded at a rate of 1 50 m/min to give a film of thickness about 1 2 microns. As it was extruded, the film was overlaid while still hot on patterned wallpaper being unwound at a similar rate from a bobbin, and the two-layered composite was subjected to a pressure of 4 to 5 atm in the nip of a pair of rollers. The resultant laminate was taken up on a reel.
The coated wallpaper so obtained had an exhanced sheen but otherwise the same appearance and flexibility as the uncoated paper.
The weight of the coated paper was not perceptibly different from that of the uncoated paper. After being hung, the coated wallpaper could be washed without damage to the printed pattern.
