Fluoropolymer Bags, Bladders & Barriers

Holscot designs and manufactures high-performance fluoropolymer bags, bladders and barrier solutions for demanding applications where purity, chemical resistance and reliability are critical.

 

 

Manufactured primarily from FEP, with options in PFA and ETFE, our solutions range from small precision-fabricated containment systems through to large-scale flexible containment and lining systems. Working directly from fluoropolymer resin gives Holscot exceptional control over quality, consistency and specification, allowing us to support both standard and highly customised requirements.
 
Fluoropolymer bags and liners can be used to upgrade the corrosion resistance of existing vessels, drums and containers, including standard industrial and NATO drum formats.  Disposable FEP liners or secondary outer bags can be replaced between process cycles, allowing highly aggressive chemicals to be safely handled.

Our containment solutions are used across aerospace, chemical processing, hydrogen and energy, pharmaceutical, semiconductor and food production industries, wherever materials must perform in aggressive or tightly controlled environments.

 

A Practical Approach to Containment

We focus on delivering the right solution for the application, not just supplying material.

  • Flexible containment bags and liners for chemical, pharmaceutical and industrial use
  • Bladders and diaphragms for controlled fluid storage and transfer
  • Barrier films and membranes for moisture and gas control
  • Hydrogen and pressurised gas components, including liner systems

Each product is engineered around the operating environment — whether that involves aggressive chemicals, high purity requirements, temperature extremes or permeation control.

 

Why Work with Holscot

  • Manufacturer, not reseller
    We process FEP and PFA in-house, giving full control over quality, lead time and specification.
  • Broad and flexible capability
    From thin-wall precision components to large diameter and complex fabricated structures.
  • Custom solutions with low minimum order quantities
    Supporting development projects, prototyping and production supply.
  • Experience with challenging applications
    Including chemical resistance, clean environments and advanced engineering sectors.
  • Ease of doing business
    Clear communication, practical lead times and a collaborative approach.

 

Designed for Demanding Environments

Fluoropolymers such as FEP and PFA offer a unique combination of properties:

  • Excellent chemical resistance
  • High purity and inertness
  • Low permeability
  • Wide temperature capability
  • Non-stick and easy-clean surfaces

These characteristics make them ideal for applications where failure is not an option and long-term performance is essential.

 

Innovation in Fluoropolymer Containment

Innovation at Holscot extends beyond traditional industrial containment applications. One example is the development of fluoropolymer barrier systems for whisky maturation, designed to reduce the evaporative losses commonly referred to as the “Angel’s Share”.

By incorporating FEP containment technology within the storage process, evaporative losses can be significantly reduced, helping to improve yield and extend storage periods. In addition, limiting the release of ethanol vapours may offer environmental and workplace safety benefits, demonstrating how fluoropolymer materials can deliver value in applications far beyond their traditional industrial uses.

 

From Concept to Production

Whether you are developing a new application or looking to improve an existing design, we can support you through:

  • Material selection (FEP vs PFA)
  • Design for manufacture
  • Prototyping and testing
  • Scaled production

Our aim is to simplify the process of specifying and sourcing fluoropolymer solutions, while ensuring performance is matched to your exact requirements.
