Our Manufactured Product Range

Diverse modern raw materials (polymers and additives) together with 35 years of manufacturing techniques and product development mean that Derek Lambert Polythene can extrude a very broad range of high quality film with properties to match most applications. We do sell our extruded film directly, but most is internally converted into bags, sheets and covers, often with added treatments and printing.

Polythene film is usually extruded from a mix of Low Density polymer (LDPE) and a Linear Low Density Polymer (LLDPE), but film characteristics can vary considerably with the raw polymer specification & quality, mix percentages, additives, extruder size and production techniques.

The mass-cost of raw material relates directly to the selling price and so using advanced polymers to produce thinner, better film capable of higher performance can reduce costs substantially. Equally, the correct use of additives and utilisation of our manufacturing techniques can also significantly impact the film quality and the gauge thickness required.
