The thickness selection of in mold label(usually referring to labels used for product packaging or decoration) should be comprehensively considered based on factors such as usage scenarios, functional requirements, and costs. The following are specific recommendations:

1. Thickness range and common choices

Conventional thickness: The thickness of the in mold label is usually between 20 μ m (micrometers) and 150 μ m.
20 μ m-50 μ m: Suitable for lightweight packaging or scenarios with high transparency requirements (such as food packaging, electronic product labels), but with weak tear resistance.
50 μ m-100 μ m: Balancing flexibility and durability, suitable for most daily packaging (such as daily chemical products, drug labels).
100 μ m-150 μ m: Suitable for scenarios that require high strength, wear resistance, or outdoor use (such as industrial products, outdoor advertising label).

2. Select the thickness according to the usage scenario

Food/Drug Packaging:
Priority should be given to selecting in mold label ranging from 30 μ m to 50 μ m to ensure transparency and hygiene, while meeting basic moisture and stain resistance requirements.
Electronic products/precision instruments:
Suggest 50 μ m-80 μ m to balance flexibility and scratch resistance, and avoid excessive label thickness affecting product appearance or operation.
Industrial/Outdoor Products:
Choose thick in mold label ranging from 100 μ m to 150 μ m to enhance tear resistance, weather resistance, and wear resistance, adapting to complex environments.
Promotion tags/short-term use:
Ultra thin films ranging from 20 μ m to 40 μ m can be used to reduce costs, but attention should be paid to their shorter lifespan.

3. Key performance indicators

Transparency:
The thinner the thickness, the higher the transparency, making it suitable for scenes where the appearance of the product needs to be displayed.
Flexibility:
The thinner the in mold label, the better its flexibility, suitable for bonding curved or complex surfaces.
Tear resistance:
Increasing thickness can significantly improve tear resistance, making it suitable for products that require frequent handling or exposure to harsh environments.
Weather resistance:
Thick label (such as over 100 μ m) are more suitable for outdoor use and can resist natural erosion such as ultraviolet radiation and rainwater.

4. Cost and processability

Cost:
An increase in thickness usually means an increase in material costs, which need to be balanced according to the budget.
Processing capability:
Ultra thin label (such as 20 μ m) require high processing equipment and are prone to wrinkles or bubbles; Thick label is easier to operate, but it may affect the bonding accuracy.

5. Recommended solution

Universal type:
75 μ m label, balancing performance and cost, suitable for most daily packaging needs.
High end model:
100 μ m thick label provides stronger protective performance, suitable for high-value or outdoor products.
Economic type:
30 μ m ultra-thin label, suitable for short-term use or low-cost scenarios.
