At Flexipol, we know nothing is more important than the secure protection and transportation of your clients’ valuable items. We are a leading manufacturer of polythene products to the courier, mailing and distribution sectors.

Our Palagan courier sacks and mailing bags are designed to be extra tough, ensuring products arrive safe and secure. They are manufactured from multilayer polythene to give your deliveries extra protection from unexpected rough handling in transit. To guarantee confidentiality, we produce high opacity films with different coloured inner/outer layered polythene. This conceals the products inside whilst promoting your company branding on the outside.

Manufactured in UK

We use multilayer extrusion machines to produce customised high performance industrial polythene. All our products are guaranteed for reliable performance and tight control over polythene thickness. Our sophisticated equipment produces consistently strong polythene. All of our bags are tested for quality assurance.
