Disposable PE gloves look like the simplest item on a food counter, and in production terms they are. Knowing how polyethylene gloves are made still helps a buyer, because nearly every complaint about them (splitting at the thumb, a seal that peels open, gloves stuck together in the box) traces back to one specific step on the line.
Here is the process in order, followed by the points to write into a purchase spec.
A material discovered by accident
Polyethylene has an unusual history. A German chemist, Hans von Pechmann, produced a waxy form of it by chance in 1898, and chemists at ICI in Britain stumbled on it again in 1933 while experimenting with ethylene under high pressure. Industrial production followed within a few years. Today it is the most widely used plastic in the world, and for gloves its appeal is plain: it is inexpensive, light, inert in contact with most foods and easy to heat-seal.
Step by step: how polyethylene gloves are made
1. Choosing the resin
The first decision is the grade of polyethylene. HDPE gives a thin, crisp glove that rustles slightly and is very low cost. LDPE and LLDPE give a softer, more stretchy film. CPE (cast polyethylene) gloves use a cast film with an embossed surface that feels smoother and grips a little better. For food-contact gloves the resin has to be a food-grade polyolefin; at Hanpak the food-contact resin complies with FDA 21 CFR 177.1520.
2. Making the film
Pellets are melted in an extruder and formed into film, either by blowing a bubble (blown film, typical for HDPE gloves) or by casting onto chilled rollers (cast film, used for CPE). Gauge control happens here. A film that varies across its width will give gloves that are fine on one side of the roll and fragile on the other. Embossing rollers can add a textured pattern at this stage.
3. Cutting and heat-sealing
This is the part that sets PE gloves apart from nitrile, latex or vinyl. Those gloves are made by dipping hand-shaped formers into liquid compound. PE gloves skip all of that. Two layers of film are fed into a machine where a heated die, shaped like an open hand, seals and cuts the outline in a single stroke. The result is a flat glove with a seam around the edge. It is fast and cheap, but the glove is loose-fitting and the seam is the weakest point.
4. Counting and packing
Gloves are stacked, counted and packed, most often 100 to a bag or box, or punched with a header hole so they can hang on a hook beside a deli counter. Inner packs go into export cartons with the size and lot printed on them.
How gloves are checked for holes
Because the barrier is only as good as the seal, the standard check is a water-leak test, similar in principle to the method set out in ASTM D5151. A glove is fixed by the cuff over a vertical holder, filled with roughly a litre of water at room temperature, and inspected for drips straight away and again after a short wait. Any leak at the seam or through a pinhole counts as a failure. Running this on samples taken through a production run gives a reliable picture of seal consistency.
What PE gloves are good for, and what they are not
PE gloves suit short, frequent tasks: making sandwiches, serving at a buffet, handling bakery items, hair-dye application, light cleaning. Staff change them often, so low cost per piece matters more than fit. They are a poor choice for long tasks, fine motor work, sharp objects or anything involving harsh chemicals. For those jobs a dipped glove is the better tool.
What to put in your purchase spec
- Material: HDPE for the lowest price, LDPE or CPE for a softer feel.
- Thickness: state it in microns, and agree a tolerance.
- Size and length: one-size or S/M/L, plus overall length from fingertip to cuff.
- Surface: smooth or embossed.
- Packing: pieces per inner bag or box, header hole or not, inner packs per carton.
- Food-contact paperwork: resin compliance with FDA 21 CFR 177.1520 and, where you need it, an SGS test report.
You can compare the two most common types on our HDPE gloves and clear CPE gloves pages. Many food-service buyers order gloves together with PE cling film to fill a container more efficiently.
When a buyer reports gloves tearing at the base of the thumb, the film is rarely too thin. More often the sealing die is running too hot and has weakened the film just inside the seam. A useful check on incoming samples is to stretch a few gloves gently at the thumb crotch: a clean seal should hold while the film itself starts to thin. If the seam lets go first, ask for the sealing settings to be reviewed before you approve production.
