Mini grip bags - as easy as one, two, squeeze.
Mini grip bags, often known by one of many other names (see below) are resealable polythene bags that are opened and closed using a plastic grip that runs across the top of the bag. The resealable grip is made of two plastic ridges (male and female) that click shut together with ease.
To close a mini grip bag:
- Pinch the end of the open grip seal between the thumb and forefinger of one hand (fixed hand)
- Place the same two digits of the other hand directly next to these, squeezing the grip seal into place as you do
- Run this second hand away from the fixed hand, keeping the grip seal squeezed between your fingers as you do so. The male and female ridges will interlock together as your fingers slide across the bag, fastening the seal as you go.
To open a mini grip bag:
- Separate the two sections of the bag that sit above the plastic grip seal, so that they are not stuck together
- Place one of these sections between the thumb and forefinger of your left hand and the other between the same digits on your right hand
- Gently pull your hands away from each other, stretching the grip seal apart as you do so, eventually opening the bag.
What's in a name?
Mini grip bag, grip seal bag, resealable bag, self-seal bag, gripper bag, grippa bag or minigrip bag. Never has a bag so small had so many names!
What's more, within each of the various names, there are even differences in the spelling of that name. Here are some of the more popular examples:
- Mini Grip, Mini-Grip or Minigrip bags
- Grip Seal, Grip-Seal or Gripseal bags
- Gripper or Grippa bags
Whatever the name, or the spelling, each of the above terms are referring to basically the same type of bag - a small rectangular polythene bag with a plastic grip seal running across the top, made of male and female plastic ridges that click shut together to enable easy opening and closing.
So, some call it a grip and some call it a seal but let's not get stuck on names. You say potato, I say potato... let's agree that the minigrip bag is a very handy little thing.
Zipper and slider - variations on the theme
Alongside the mini grip bag and its many names sit two other resealable bags, based on the same principle but with a slight difference in the locking mechanism:
- Zipper (also ziplock, zip-seal and ziplite) bags - Premium quality reclosable bag with a durable zip fastener running along the top of a coloured wallet opening. Perfect for storing documents, these bags are ideal for handing out publicity material at exhibitions.
- Slider grip (or slide grip) bags - A 'simple classic' self-sealing bag with a plastic slider grip seal closure. Ideal for transporting offices documents or college work, these bags provide a professional packing solution at budget prices.
When is a self-seal bag not a resealable bag?
A resealable bag is, as the name suggests, a bag that can be used over and over again.
Mini grip, zipper and slider bags, for example, are all types types of resealable bags. In these three instances, however, the bags in question are also self-seal bags, although this is not always the case.
A self-seal bag is one that can be sealed without using an additional sealant - such as glue or tape - or without the need to seal the bag using heat to melt and bond the plastic, known as heat-sealing.
All resealable bags are self-seal bags, but not all self-seal bags are resealable bags. In fact, probably the most common form of self-seal bag is not a resealable bag.
Mailing bags are used to send documents and packages by post or transit. A self-adhesive strip running along the top of the bag allows the bag to be sealed and the contents delivered safely and securely with the minimum of fuss.
Unlike resealable bags, mailing bags are opened by breaking the seal or ripping the bag open, which often acts a security feature to guarantee one-time use. As such mailing bags are self-sealing bags but, unlike grip seal or zip seal bags, they are not normally resealable bags (unless specifically engineered to have a reusable adhesive.)

There are lots of reasons why mini grip bags are extremely useful. Here are just a few:
- Reusable & resealable - they are durable and can be used time and time again

And that's just to name a few! There are plenty of reasons to get hold of some mini grip bags, so why don't you find out for yourself?
Hints and tips for purchasing mini grip bags:
Mini grip bags come in all shapes and sizes and cater for storing a variety of products, so we have put together a few handy tips for making sure you buy the right mini grip bags for the job in hand.
Think carefully about what it is you want to store and the specific needs of that product before you purchase your mini grip bags. For example:
- How big are the items that you wish to store? Mini grip bags aren’t all mini! They come in a variety of sizes ranging from 1.5” x 2.5” up to 15” x 20”, so you have a wide range of options available to you. Think before you buy!
- How many items do you want to store in the same bag? Consider what you need to store in each bag and how many of these you want to store in each bag. This will help you choose the most appropriate size. Always make sure that your bags are big enough to hold your product without overfilling it and potentially causing the seams to split.
- Do you need to categorise or colour-code the items? Coloured mini grip bags provide a quick and simple sorting solution, while the vivid colours - red, blue and green - will liven up your packaging. For more detailed content indexing, labelled mini grip bags allow users to detail the contents on the outside of each bag.
- Do you need to keep the content of the bags private? If so, then black mini grip bags could be just what you are after. They are just like standard mini grip bags and come in a range of sizes, but the opaque black plastic ensures that no-one can see through the bag.
- How abrasive or heavy are the items that you wish to store? Are you planning to store particularly rough, sharp or heavy items? If so, then you should consider heavy duty mini grip bags. Made from a thicker - 350 gauge - polythene and available in a range of sizes, these bags are strong enough for the toughest of jobs.
- Are your mini grip bags for a specialist use? If standard mini grip bags aren’t suitbale for the job in hand, remember that a range of specialist mini grip bags are available. These include, among others, anti-static mini grip bags (for the electrician), grip seal carrier bags (for the retailer) and specimen bags (for the medical professional or forensic expert).
