Keyhole laser welding of polymers is a subject well covered and researched, but relatively little information exists regarding the welding of thin polymer films, particularly to a heavier substrate. This paper presents the design of a suitable test apparatus for laser welding thin film to a heavier substrate, and shows the results of an investigation into the feasibility of laser welding multi-layer polymer film lids to tubs for the manufacture of aseptic food containers. A consistent weld, free from defects, is the key to process success. Typical welding defects have been synthesised in order to investigate, and consequently remove, their cause. The result is a reliable welding method based on even film clamping. With careful attention to machine design, a seal of high mechanical strength and chemical integrity is possible.read more

Welding processes for plastics
TL;DR: Welding is particularly attractive for thermoplastic part assembly because joining times are often very short, enabling high throughput as discussed by the authors and it typically produces strong joints, tolerate contaminated surfaces, and successfully joins such difficult-to-bond substrates as polyolefins.
