A product label is often the first thing a customer sees before picking up your product. It communicates your brand, builds trust, and delivers essential information at a glance.
But not all labels work the same way. Each label type serves different packaging needs, application methods, and industries. Choosing the right one affects how your product looks, performs, and sells on the shelf.
Here are three types of product labels and how they are commonly used.
1. Pressure Sensitive Label
Pressure Sensitive Label (PSL) is a label with an adhesive layer on the back. It sticks to surfaces with light pressure, requiring no heat or water to apply.
Because of its flexibility, PSL is one of the most widely used label types across industries. It works on a wide range of containers, including:
- Bottles and jars
- Tubes and pouches
- Boxes and cartons
- Flexible packaging
PSL suits products across food and beverage, cosmetics, personal care, pharmaceutical, household, and chemical industries.
For small runs, you can apply PSL by hand. For high-volume production, a labelling machine handles the process faster and more consistently. PSL also supports a wide range of finishing options such as lamination, foil stamping, embossing, and varnish, so you can achieve both function and strong shelf presence.

2. Shrink Sleeve Label
Shrink Sleeve Label wraps around the full body of a container, giving you 360-degree coverage. During application, heat causes the sleeve to shrink and conform to the exact shape of the container, creating a smooth and seamless finish.
This label type works well for:
- Bottles and jars
- Uniquely shaped containers
- Products that need full-body decoration
Shrink sleeve labels are common in food and beverage, cosmetics, personal care, household, and pharmaceutical industries.
For high-volume production, automatic sleeve applicators and heat tunnels handle the process efficiently. For smaller runs, semi-automatic applicators work well, where the sleeve is placed manually onto the container before heat is applied.
Shrink sleeve labels offer strong durability and consistent print quality, making them a reliable choice when full-body branding is a priority.

3. In-Mould Label
In-Mould Label (IML) takes a different approach. Instead of applying a label after the container is made, IML fuses the label directly into the packaging during the molding process.
The label is placed inside the mold before the container forms. As the plastic sets, the label becomes part of the container itself. The result is a label that is scratch-resistant, moisture-resistant, and built to last.
IML works best for rigid plastic containers such as:
- Buckets and tubs
- Cups and bowls
- Bottles and canisters
It is widely used in food and beverage, cosmetics, personal care, household, and chemical industries, especially for products that need a premium appearance with long-term durability.

Which Label Type is Right for Your Product?
Each label type has its own strengths. PSL offers flexibility and broad compatibility. Shrink sleeve delivers full-body coverage. IML provides durability and a seamless finish.
The right choice depends on your container shape, production volume, industry requirements, and the look you want to achieve.
