What is a ziplock bag?
Ziplock bags are clear polythene bags fitted with a simple ziplock fastener for easy storage of a wide range of products. They are part of the zip seal group of bags and the wider family of self-seal bags and resealable bags.
The classic ziplock bag features a ‘slidergrip’ ziplock seal that runs along the top length of the bag. This features a clasp that slides along the bag seal and, depending on the direction of travel, either opens or closes the two sides of the bag together. This mechanism works much in the same way as a zip fastener, which gives the ziplock bag its name.
The Ziplock bag - along with the ziplite bag and the zipper bag - provides a professional packing solution for a wide range of a material. Whether you need to carry project work to school, showcase a portfolio of your work, present publicity material to clients or impress delegates at a conference, there is a ziplock bag to help you get the job done, whatever your budget.
Zipper, ziplock, ziplite - variations on a theme
The zipper bag is the number one premium quality plastic bag with a zip fastener. Made with a durable metal zip and with a distinctive red profile running along the length of the bag, the zipper is a top-of-the-range bag and thus perfect for presenting material at conferences.
The ziplock bag is a brilliant budget alternative to the zipper bag. It serves much the same purpose, but with a plastic slider grip rather than a metal zip. Available in a range of sizes, the ziplock is a 'simple-classic' design that offers a professional packing solution for a variety of tasks.
The ziplite bag is a close derivative of the ziplock, but weighs in at less than half the weight for the same size bag - hence the name. Ziplite bags provide high clarity to showcase your products and come with a bottom gusset to allow for the packaging of bulky items.
Zip seal & grip seal bags - don’t get confused!
The grip seal bag, often known as the mini grip bag or gripper bag, is a resealable polythene bag and a cousin of the zip seal or ziplock bag but, whilst sharing many similar features, there is a distinct difference between the two.
Rather than a zip, grip seal bags are opened and closed using a simple plastic grip seal that runs along the top of the bag. This grip seal is comprised of two plastic ridges (one male and one female) that fit neatly one inside the other to clasp the bag shut when squeezed together.
Grip seal bags are available in an extensive range covering a wide variety of uses, including plain, coloured, labelled and heavy duty bags, as well as specialised grip seal carrier bags, antistatic grip seal bags for electrical components, black grip seal bags for extra security and specimen bags with labels - popular with doctors, police and forensics experts!
So, whilst related and just as useful in its own many ways, the grip seal bag is not to be confused with the ziplock or zip seal bag. And with so many fantastic options to choose from, why choose a bag that’s not 100 percent right for you?
The zipper bag - a winner at conferences!
Major conferences are often among the most important events in an industry’s calendar. They offer companies small and large a unique opportunity to impress the people at the heart of their industry, show competitors that they mean business and showcase their products to their target market, with the potential to win new or repeat custom.
Companies often break the bank on publicity material or spend hours drawing up impressive documents to present to conference delegates only to do so poorly - either as loose bits of paper that get easily damaged, separated or lost, or in a cheap flimsy plastic sleeve that often says more than the material it contains. No matter how good your material is, if you don’t present it well you risk making the wrong impression from the outset.
Ziplock bags prevent this. Smart and sturdy, they show that you are professional from the outset. Their clear exterior allows you to show off your best publicity materials inside the bag, while the simple ziplock fastener allows delegates to access your reports and brochures with ease. As delegates invariably collect lots of material to read after the conference, a ziplock bag will help ensure that your company leaves a lasting impression and increases the chances that your visitors become your customers.
Here are just some of the industries from which companies regularly turn to the zipper or ziplock bag for impressing delegates at conferences:

Tip: Use Ziplock Bags With Your Handi-Vac
Ziplock bags only work properly when the seal is clean and the bag mouth is flat enough for the pump to grip, so a failed vacuum often says more about handling than about the bag itself. A small wrinkle, a crumb on the sealing strip, or a weak pump head can leave enough air behind to spoil the result. In packing terms, trapped air makes bags harder to stack, less stable in a case, and more likely to spring open below pressure. For dry products, that matters less than for items needing a tight barrier, nevertheless the pack still requirements a proper closure. A fast check on the seal path normally saves a wasted batch.
Economical Self-Seal Bags - 4 x 8" - 4 Mil - Case of 1000
A 6 x 9 inch self-seal bag suits small parts because it gives only enough room for loading without leaving a lot of wasted space. That tighter fit makes a proper contrast in storage, where excess air between items steals shelf room, and in dispatch, where fat packs can make cartons and pallets sit badly. The format also assists on the packing line because operatives can load and close each bag fast without fighting oversised packaging. For repetitive select-and-pack work, that means cleaner handling, less snatching at stock, and a lower chance of parts being crushed or lost in transit.
Best match for self seal bags
Self seal bags only perform properly when the film, adhesive and lip profile are matched to the packing job. A bag can see tidy on inspection and still cause trouble if the gauge is inconsistent, the tack is patchy or the opening is awkward for gloved hands, because the operatour then loses time forcing the pack to behave. That sort of friction soon shows up on the bench as slower throughput and more rework. For small parts, powders and returned products, the closure requirements to stay sound through repeated picking and handling without splitting the film or lifting at the seal. A sensible specification retains the process moving and reduces handling damage.
Mini grip bags are a tidy reply when small parts must stay in the proper count and reach the packing bench without drama. A bag that closes cleanly first time saves time at issue, cuts down on spillage, and avoids the sort of floor loss that happens when loose screws, seals or samples tip out of a half-closed pack. The feel of the film matters as well, because a gauge that is also light can make the bag awkward to handle, while a heavier film can slow filling and make the pack see fat in a carton. That balance assists retain line flow proper and reduces handling damage.

Grip seal bags earn their place because they combine simple containment with fast, repeated access on the packing line. The proper value lies in the method the film and closure behave below normal warehouse abuse, where small parts, dust and constant opening can expose weak gauge or a poor interlock straight away. A bag that is also flimsy splits at the corners and creates handling damage, while one that is also heavy wastes material and occupies cartons without adding much protection. Good stock selection is so about matching film strength to the load and keeping the seal consistent from batch to batch. That balance saves time at select face and avoids nuisance rework later.
Zipper reclosable bags work optimal when the closure is matched to the filling job and the method the pack will be handled later. A soft LDPE body gives a bag enough give to seal cleanly, fold flat in transit, and stand up to repeated opening without cracking at the edges, while the zipper strip retains contents secure between uses. On a busy line, wicketed formats can improve filling speed, and a slim deli-style bag is easier to manage for counter service or small part packs. The practical selection is the one that fits the product flow, not the one that merely sees tidy on a shelf.

packaging supplierble bags in transparent 2 mil polythene suppliers sit in a useful middle ground because they are robust enough for repeated picking and packing without adding unnecessary weight to a consignment. The gauge gives enough puncture resistance for small components, paper items and secondary bagging, while still keeping the film supple enough for fast manual use on a busy line. A closure that shuts properly across its full width matters only as much as the film itself, since weak engagement can lead to dust ingress, curled edges and bags opening again in storage. That kind of consistency makes daily handling easier and reduces avoidable misuse.
polythene suppliers bags are valued because they are light, fast to pack and easy to handle, nevertheless those same properties also make them attractive for strange or suspicious consignments. A superb mailer relies on the proper film gauge, consistent resin quality and enough puncture resistance to survive sorting belts, stack pressure and rough handling without adding needless weight. Opaque film assists keep safe privacy and conceal returns, yet it also makes visual checks harder when secondary bagging is used to retain loose items together or disguise what is inside. The practical reply is better specification control, with proper seals, batch coding and mono-material building that still enables recycling. On a busy dispatch floor, that balance determines whether a bag is a clean logistics tool or only a convenient cover.
Ziplite bags rely on the method the film runs on the packing line, not only on how light the gauge sees on paper. A thinner polythene suppliers can still cause trouble if it feeds badly, folds unevenly or loses its shape amid fast filling and cartoning. Soft film may curl at the edges and slip in the machine, which leads to stoppages and wasted time at the bench. A sensible balance gives enough body for stacking and handling without adding unnecessary material, so the line retains moving at a proper pace.
(XR102) PP Zipper Bags
PP zipper bags give a simple closure that suits repeat opening without losing the contents, which is why they are broadly chosen for parts, samples, and small shopping packs. Polypropylene has a firmer feel than soft polythene suppliers, so the bag retains its shape better on filling lines and sits neatly in cartons or tote boxes. The zipper track requirements clean profile control amid converting, because a poor seal or uneven moulding can leave the closure hard to lock by hand. Good gauge selection also matters, since a film that is also light can split at the corners, while one that is also heavy adds waste and stiffness.
Use a ziplock bag to make your own Zippy puppet!
On a lighter note, the ziplock bag also provides a fun and cheap way to amuse small children or easily-pleased adults, by making your very own puppet like Zippy - the loud wide-mouthed character from 1980’s children’s TV show Rainbow.
Required materials:
- One ziplock bag (size optional)
- Two soft fuzzy felt balls (from a craft pack)
- Some glue
- Some felt-tipped pens (optional)
Directions for making your Zippy puppet:
- Take your ziplock bag and lay it out on the table, with the ziplock edge facing you
- Take your two felt balls and have them ready to stick on your puppet as eyes
- Place a small amount of glue in two places alongside the near edge of the bag, halfway between the middle and either end of the zipper opening
- Place the first felt ball on one of the glue spots and squeeze down for a few seconds
- Repeat with the second felt ball and the other glue spot
- Leave the glue to dry (time depends on the type of glue)
- Once dry, pick up your ziplock bag and make the bag open and close to resemble a mouth. You can even zip the mouth shut just like Zippy
- If you like, you can even use a felt-tipped pen to draw a mouth inside the bag and some pupils on to the eyes to make the puppet even more realistic (optional)
And there you have it - hours of fun guaranteed, with the right audience. Enjoy your Zippy puppet!
