How to choose the raw materials of self-adhesive labels

When selecting the raw materials for self-adhesive labels, multiple factors need to be considered comprehensively to ensure that the labels can meet the specific application needs. Here are some key selection principles:

First, understand the basic composition of self-adhesive labels

The self-adhesive label is mainly composed of three parts: surface material, pressure sensitive adhesive and backing paper. The surface material directly displays the visual effect, the pressure sensitive adhesive is responsible for the adhesion of the label, and the backing paper plays a role in protecting the pressure sensitive adhesive.

Second, consider specific application scenarios

Industry characteristics:

Food and drug industry: the materials are non-toxic and environmentally friendly, and must comply with relevant regulations and standards. Coated paper, PET and other materials are often used in these fields.

Daily chemical products: may need waterproof, oil proof performance, PE, PP, PET and other materials are more suitable.

Electronic products: There are high requirements for the temperature resistance and chemical resistance of the label, and the PET material has excellent performance.

Anti-counterfeiting labels: fragile paper, special anti-counterfeiting materials, etc., are ideal.

Use environment:

Wet environment: Choose materials with good water resistance, such as PET, PVC, etc.

High temperature environment: need to consider the heat resistance of the material, PET is a good choice.

Chemical contact: To ensure that the material is resistant to chemical corrosion, PET and some special synthetic paper have this property.

Label object:

Rough surface: requires a large amount of adhesive coating or good flow of materials to enhance adhesion.

Soft surface: Choose soft, flexible materials to avoid wrinkling or falling off after labeling.

3. Evaluate the performance and cost of materials

Features:

Adhesion: Ensure that the label can be firmly attached to the target object and is not easy to fall off.

Durability: Consider the waterproof, oil-proof, wear-resistant properties of the label to meet the needs of long-term use.

Visual effects: Select the appropriate gloss, color and printing adaptability according to your needs.

Cost:

The cost of different materials varies greatly, and it is necessary to choose according to the budget and actual needs. The cost of ordinary paper labels is low, and it is suitable for high-volume and low-cost application scenarios. High-grade plastic or metal labels cost more, but have better durability and visual effects, suitable for high-end products or special uses.

4. Refer to professional advice and cases

Consult experts or suppliers in the sticker label industry to understand the specific characteristics and scope of application of different materials.

Refer to the successful cases in the industry to learn about the selection and effect of label materials in similar application scenarios.

5. Sample testing

Sample testing is recommended before finalizing the material. Key indicators such as adhesion, durability, and visual effects are evaluated through actual labeling tests to ensure that the selected material can meet the actual needs.

To sum up, the selection of raw materials for self-adhesive labels is a comprehensive consideration process, which needs to be made according to various factors such as specific application scenarios, material properties, cost budgets and professional advice.
