What are polybags?

A polybag is basically a bag made of plastic, used for packaging or preserving a range of items.

In the world of packaging and fulfilment, polybags is a common term and often refers to polyethylene (PE) packaging which is a commonly‑used type of plastic.

Polybags for packaging and shipping come in different shapes, sizes and types, making them great for a range of products and orders.

They are durable and versatile, making them cost‑effective and protective, and when used correctly can help keep products safe throughout the distribution process whilst optimising shipping costs.

What can polybags be used for?

Polybags can be used for a wide variety of items, including:

• Books and magazines
• Printed materials
• Clothing
• Boxed items like cosmetics, video games or DVDs
• Other boxed items

Thinner polybags are useful for lightweight items, while heavy‑duty polybags can protect heavier, bulkier or sharp products.

Their varied closure systems make them ideal for almost any product, keeping everything sealed and safe during packing and shipping. Open‑ended bags can be sealed using heat for extra security, while zip‑lock polybags are reusable and give a clean, high‑quality finish.

Why choose polybags for packaging?

Their flexibility in size, shape and seals makes polybags perfect for products ranging from heavy and bulky to light items and boxed goods.

They’re a light, cost‑effective alternative to cardboard boxes—ideal for small, soft or non‑fragile goods, reducing shipping costs and minimising filler.

Many polybags are recyclable, and some are made from 100 % recycled or biodegradable materials, helping reduce environmental impact. Reusability also curbs waste.
