PP self-adhesive labels are self-adhesive labels that use polypropylene (PP) plastic as the base material. The properties of polypropylene plastic give PP self-adhesive labels good abrasion resistance, waterproofing, and chemical resistance. These characteristics allow PP self-adhesive labels to maintain good performance under various conditions, and they are widely used in the fields of food and beverages, medical, chemical packaging, household goods, etc.
Structure and Manufacturing #
PP self-adhesive labels mainly consist of the following layers:
- Surface material: usually polypropylene plastic, used to accept printing ink.
- Adhesive layer: used to stick the label to goods or other surfaces.
- Backing paper: to protect the adhesive from damage, and to be torn off when used.
The process of making PP self-adhesive labels includes selecting polypropylene as the base material, applying adhesive, attaching the backing paper, printing, and cutting.
PP self-adhesive labels have the following characteristics:
- Abrasion resistance: Polypropylene plastic has excellent abrasion resistance, allowing PP self-adhesive labels to maintain good performance even under harsh conditions.
- Waterproof: Polypropylene plastic has excellent waterproof properties, so PP self-adhesive labels can be used in damp environments and are also suitable for labels of liquid products.
- Chemical resistance: Polypropylene plastic has good resistance to many common chemicals, making PP self-adhesive labels suitable for use in chemical environments or as labels for chemical products.
Application Range #
Due to their abrasion resistance, waterproofing, and chemical resistance, PP self-adhesive labels are widely used in the following fields:
- Food and beverages: PP self-adhesive labels can be used to label food and beverage packaging, such as bottles, cans, bagged food, etc.
- Medical: Medical equipment, pharmaceutical packaging, etc. usually use PP self-adhesive labels.
- Chemical packaging: Due to the chemical resistance of PP self-adhesive labels, they are often used for chemical packaging.
- Household goods: PP self-adhesive labels are also commonly used for various household goods labels, such as detergents, washing liquids, etc.
In general, PP self-adhesive labels are widely used in various industries and products due to their abrasion resistance, waterproofness, and chemical resistance.
