MG Polymer would never compromise product quality for competitiveness.

On our manufacturing side, we quality test at all stages of production, before during and after production of an order.  We are strong believers in preventing poor quality and ensuring the delivery of consistent production.  We make regular capital investment in our manufacturing resources and capabilities, making use of improved manufacturing techniques but avoiding expensive leaps into 'state of the art' machinery unless value for money is proven.

Where we import goods to retain competitiveness, we foster long term supply relationships and do not chase the latest bargain price producers - only then can we guarantee consistent products for our customers.

Food Contact

We confirm that all virgin polythene supplied by MG Polymer complies with the relevant legislation on food contact including Great Britain and the European Union.

• Great Britain: Statutory Instrument, 1998 No. 1376 and BPF-BIBRA (1995), Polymer Specification 4, Polyethylene

• EU: Commission Directive 90/128/EEC, 92/39/EEC, 93/9/EEC, 95/3/EEC and 96/11/EC, Section A.




The polythene film extrusion process involves blowing up a molten bubble of film and then cooling and cutting it to shape.  This is a technically advanced process and is affected by external factors (such as humidity and heat) and by the stretchiness and flexibility of the film.  Whilst we strive to obtain exact dimensions, a degree of manufacturing tolerance is therefore always required on every product.

• Width: Plus or minus 3mm (0.125") or 2%, whichever is greater. If you need a minimum width, please discuss with us.

• Length: Plus or minus 6mm (0.25") or 2%, whichever is greater. Please note that all measurements are cut to cut and will therefore include a bottom skirt of about 8mm on end weld bags (apart from grip seal bags where length is measured from the grip seal to the bottom of the bag).

• Gauge: Plus or minus 10%.

• Quantity: For manufactured goods only, Plus or minus 10%.

Please do not hesitate to contact us to discuss any specific tolerance required on your product.
