Who are Polybags?

Polybags Ltd is not just the best value international distributor of packaging materials. Unlike most packaging companies Polybags controls its own factories and can therefore extrude polyethylene film and make polythene bags to suit any order. This is important for several reasons:

  1. If you can't find *exactly* what you want in our extensive online stock list then Polybags can manufacture film or manufacture bags to your *exact* specifications

  2. No middle man means that you eliminate distributor markups and we deliver bags and film to you at the best possible price

  3. We can make film and bigs quickly and despatch directly to you saving yet more time. In fact we specialise in fast turnaround orders

  4. We can make film and bags in the quantities you require, when you want it; you don't have to wait 3 months for the next stock shipment to arrive

Our manufacturing capacity

We run 13 extruders (a combination of British, Italian and Taiwanese made machinery), a number of which have film treaters, in-line printers and double unwinds for sheeting production. All in-house extrusion scrap is recycled using our Erema Reprocessing plant with reprocessed grades stored in internal silos.

All our extruders are also linked to sales with a real time scheduling system, so we can give immediate information on lead times and make adjustments where required. Ask our sales team about the system as they love it!

After a major investment project with 3 new extruders, recent extrusion investment includes new silos, print units, improved air rings and chillers, a new wide winder plus jumbo take-off units.

Information on Polybag

Poly bags, also known as polythene bags, have a variety of uses in many industries. In the apparel, garment, sew goods, fabric and related industries, poly bags are use to protect goods during shipment from dirt, dust, and moisture. Material Concepts is a leading supplier of poly bags in various styles, sizes, shapes, and densities. Our styles include:

  • Flat poly bags
  • Poly bag tubing
  • Reclosable poly bags (also known as resealable or ziplock bags)
  • Wicketted poly bags
  • Gussetted poly bags
  • Garment poly bags
  • Poly film
  • Poly sheeting

Uses and Application for Poly Bags

The uses for poly bags are virtually without limit! Whenever there is a need to protect an item during storage or shipment, Material Concepts can supply a poly bag that is right for the job. Lighter density poly bags are a good choice for items that are not heavy and require only a simple shield from their surroundings. Heavy density poly bags keep your goods safe from harm in more abusive environments where dirt, dust, moisture, movement, etc. are factors that may damage your goods.

The shape of the bag is also an important consideration in some cases. Flat poly bags are general purpose bags that are often used where a clear presentation at a low cost is desired. We offer wicketted poly bags and gusseted poly bags for applications where the shape and style of the poly bag is vital to how it will be used. For protection against moisture in particular, a reclosable poly bag is suggested, keeping your goods safe while allowing for easy opening and closing.

Garment poly bags are specially designed and shaped for use with shirts, coats, pants, etc. for protection and ease of use in apparel applications. Poly film and poly tubing are used where large quantities are required and use of a roll of the film or tubing is a good solution.

Polybags range of materials

Polybags specialises in the following film materials

  1. Standard Melt 2 Low Density Polythene (LDPE) Films for general packaging applications.
    Suitable for the majority of general film and bag requirements, our standard film blend has an anti-blocking agent and a slip agent to help during the film extrusion process and to produce a product that it easy for you to handle and open. Film without slip or with additional slip concentrations is available on request and our film is certified Food Grade Approved.
  2. Low Slip Melt 1 LDPE Films for shrink film and sack applications
    This film has a higher molecular strength and is designed for shrink applications. During the extrusion process the film is expanded into a bubble whilst molten and then quickly solidified, effectively "sealing in" the shrink effect which is released when heated by a shrink gun or heat tunnel. This grade also has no additives which means it has a less slippy feel and is suitable for stacking. Its higher molecular strength than the Standard Melt 2 film also means it is used to manufacture heavy duty sacks.
  3. High Melt 4 LDPE Films for thin dust cover / garment cover uses
    A soft film which has limited strength properties but is very flexible and so we are able to downgauge during extrusion to very thin films of 80gauge (20micron) or less. This can save significant quantities of film and so cost to you where the application is very light duty, in particular for garment and dust covers.
  4. High Tensile Films for maximum strength to thickness requirements
    A blend of polymers including Medium Density Polythene which creates the ultimate strength film at thin thicknesses. Clarity is not as good as other films nor is flexibility (film has a slight rough crinkly feel) but the material is perfect for thin food grade tint sheets and other tinted and coloured films.
  5. Metallocene Blends for premium high clarity Films
    Metallocene is a term for polyethylene raw material that has been manufactured in a slightly different way to usual using a metallocene catalyst, resulting in film with extremely good optical and strength properties. There is additional cost in manufacturing Metallocene raw material and so the film is more expensive but this may be justified where high film clarity and strength is required.
  6. Electroconductive Blends for electrically sensitive packing
    Electroconductive film is based on special blends of highly conducting carbon Blacks compounded into low density polythene. The film is therefore electrically conductive and designed for handling and packaging electrostatic sensitive devices. As a result of its spark free properties, it is also used to store explosive devices although it can also be used for general packaging to avoid dust attraction on components.
  7. Biodegradable Film for composting applications
    Our biodegradable film has an additive blend which provides first oxidative and then biological degradation of the material, typically within 6 months to 2 years in a landfill site or standard composting system. Compared to many other environmental alternatives, this is a cost-effective, strong and recyclable film solution.
  8. Reprocessed Films for low cost and low quality uses
    Reprocessed Film is extruded on request. The main problem is lack of recyclable material available as it is such a popular option. Although product quality is not as good as virgin material, recycled film is a low cost and extremely environmentally beneficial film solution and we will always offer it whenever we have sufficient material.
