Polythene Bag Manufacturing
Polythene.co.uk is a specialist polythene website but that doesn't mean we only deal in polythene sheeting.
This website is brought to you by Polybags - the UK's number one polythene manufacturer - and, as the name suggests, we know a thing or two about polythene bags as well!
Polybags stocks over 100 million plastic bags - from carrier bags to mailing bags and everyday black bin bags to specialist waste sacks.
Any size, shape, colour or strength, we've got the polythene bags you need - and if we don't, we can make them for you.
As Polybags are manufacturers, we make all of our own plastic bags so if you have very specific bag requirements, then we can meet these for you.
What's more, the fact that there's no middleman between you and us means that your polythene bags get to you quicker and cost less. It's a win-win!
How polythene bags are made
The manufacturing of polythene bags begins with the extrusion of polythene film, which is blown and then flattened into a layflat tube using a blown film extrusion line.
Polybags operates 13 extrusion lines around the clock to produce polythene on a 24-hour basis. Some polythene stays in the form of tubing or sheeting - see polythene film manufacturing for details - whilst the remainder is converted into polythene bags, which we focus on here.
The bag-making process begins as the polythene layflat tubing moves from the extrusion line around a series of rollers to a conversion line - or converting station - where it is treated, printed, cut and sealed in a specific way to convert into a series of a particular type of polythene bag.
Sometimes rolls of layflat tubing are wound onto the roll straight off the extrusion line and then loaded onto the beginning of the conversion line at a later time to begin the bag-making process. Either way, by the time the polythene film reaches the conversion line it has been pulled tight around the rollers to provide sufficient tension to treat, cut and seal the polythene bags.
If bags are being printed then they first pass through a treatment point to prime the surface of the polythene for printing, before passing through the printer itself.
At this stage, Polybags can customise the polythene bags with a company logo or design of your choice, printed on one or both sides of the bag. See the printed polythene bags section below for more details on our bespoke printing service.

Its been raining for days and there’s a lot of heavy downpour in our cities, at this time British’s can clearly see the uselessness of our drainage systems and our waste disposal system. its unimaginable the amount of filth that washes us after these rains, yet all we see are pictures in newspapers and on television nevertheless none is tackling the main issue at hand. More than 3/4th of he waste washed up is plastic waste, black polythene suppliers bags and cans (if im not gross, that is how most food in United Kingdom is presented now). we have seen the attempt by plenty to start a recycling process for plastic bottles. i have witnessed myself and even the collectours select the bottles they favour and leave the unattractive ones. currently United Kingdom is utilising recycled bottles to manufacture electricity. when the United Kingdom realised pollution caused by bottles and plastic bags, they changed all factories manufacturing plastic bags to paper-bag industries. This is where i start to talk about Democracy, a pretty big word that has been given a small meaning in our Polybags( i wont talk about the banking issue in this article). If United Kingdom was to say that people should absolutely change from plastic bags to paper bag, and implement strict laws to ensure that production and supply of plastic bags be ceased or small to biodegradable material only, after maybe 6 months to a year a big change will be seen in out streets. nevertheless before this can effectively be passed, i can assure you there will be riots by plenty. If people determine not to change their attitude towards situations, the situations must be tweaked to change the mind. paper bags are equally recyclable and biodegradable. if you still want to litter the streets, someone will make money off of you. see if people wont retain their paper bags below their beds. Our democracy requirements to be firm and be bold enough to take decisions that will transport the nation forward. a big example is going to the gym, if you proceed to see at the weights, you acquire none, if you feel a small hurt and you quit, you acquire none also, nevertheless if you work through the hurt and sweat RESULT is all you acquire. United Kingdom can only transport forward by making stern sacrifices for the nation. also much consideration for people masked by the illusion of democracy has taken us one step forward and three steps back. we must work harder for our nation. thank you for your time.

United Kingdom: In 2004, United Kingdom prohibited shops from giving away plastic bags to their clients. The British government introduced tax smashs that encourage companies to recycle, instead of manufacture, plastic bags thereby creating a totally new market for environment-friendly bags and as of 2008, non-biodegradable polythene suppliers bags are illegal. Eventually, the country is looking to ban other types of plastic and is even hinting at the possibility of becoming the world’s first plastic-free nation. Its constitution recognises that “all citizen is entitled to a healthy and satisfying environment.” It also underlines each citizen’s responsibility to “keep safe, safeguard and promote the environment”.

Welds, gussets, skirts & handles
Polybags can manufacture polythene bags in any way you require to suit your specific needs. Our 12 converting machines allow us to cut, shape and seal polythene bags in all manner of ways to make them the ideal fit for your job.
Whilst you don't need to know how this process happens - we can take care of everything! - the brief guide below provides a few details for those of you interested in the bag-making process and how we convert polythene film into the widest range of bags available online.
As the polythene leaves the printing station, it is cut to the correct size for the bags in question, using either side-weld or bottom-weld production - terms that we explain below (see bullets & diagrams) along with a few others that you might come across in the polythene bag-production process.
- Bottom-weld bags - using a layflat tube of polythene as the starting point, bags are created with a single weld across the width of the tube, providing a strong seal at the base of the bag, and cut to length at the top of the bag. Also known as bottom-seal bags, these bags are generally stronger than side-seal bags.
- Side-weld bags - using centrefold sheeting as the starting point, the fold in the sheeting becomes the base in the bag, which is welded together on both sides, leaving the top of the bag open. Also known as side-seal bags, these bags are usually more economical to produce so keep costs down, although they aren't as strong as bottom-weld bags.
- Gussets - when extruding polythene, the film or tube can be folded to provide extra volume in polythene bags produced off that roll. Gussets can be inserted into bags at either the base or along the sides (or both) and, when opened, provide extra space in the bag for large or bulky items.
- Skirts - a polythene bag's skirt is is the strip of polythene that sits outside of the bag, attached to the seal. Skirts can be found either at the base of the bag (in bottom-weld bags) or along the sides of the bag (in side-weld bags).
As well as being cut and welded to size, the bag-conversion process also involves cutting handles out of the bags and/or adding seals to the bags where necessary.
Bag handles are punched out of the bag by a heated tool in the same shape as the desired handle. This melts and punches through the polythene to leave a handle in each consecutive bag working its way through the conversion line.
This same method can be used to add perforation holes to the bag - usually around 6mm in size - which add ventilation to the polythene bag where required.
Finally on the conversion line is the process of adding a seal to the polythene bags, when required. Polythene bags may close in a variety of ways, but two of the most popular seals produced by Polybags are as follows:
- Adhesive-strip seal (single-use seal) - this type of seal is found on bags with a flap or lip which is folded down to seal the bag, such as mailing bags. These bags are manufactured using J-fold sheeting, with the extra flap of polythene used as the lip of the bag, whilst the lip itself has a double-sided adhesive strip stuck to it. One side of this adhesive strip connects it to the bag, whilst the other side is covered with a thin plastic film which the user tears away when ready to seal the bag, before pressing down to close. The tight bond formed by this seal means the polythene bag has to be cut or ripped to be open, hence bags of this type are not resealable.
- Grip or zip seal (reusable seal) - these types of seals turn a sealable bag into a resealable bag. The grip seal - also known as the minigrip or grippa - is an integral plastic seal which is cut and heat-bonded to the bag along its opening during the final stages of the conversion process. The seal is formed by a single plastic strip inserting directly in between two adjacent plastic strips on the other side of the opening. This seal simply squeezes tight shut between the fingers, whilst it can be pulled open with the gentlest of tugs. Zip seals - which include slidergrips, zippers and zip-lock bags - feature an external zip or plastic clip which can be pulled up and down the exterior of the bag to open and close the seal.
