I. What are PE label materials?
PE (Polyethylene) label material is one of the most widely used flexible label substrates in current packaging printing, cosmetics and beauty products, food industry, chemical logistics and other fields.
It has core advantages such as water resistance, oil resistance, excellent flexibility, strong adhesion, high cost performance and excellent chemical stability.
Instiker has been deeply engaged in the field of functional label materials for many years, focusing on the research and production of high-quality PE self-adhesive label materials.
It optimizes product performance for complex usage scenarios in multiple industries and launches various dedicated substrates such as milky white PE, transparent PE, and weather-resistant PE, which are suitable for special bottle shapes, damp oil stains, outdoor weathering, low-temperature storage and other harsh conditions.
It provides standardized and customized label solutions for various industries.
II. The application scenarios of PE label materials
1. Cosmetics and personal care industry
Most daily care products are in the form of flexible tubes, special-shaped pump heads and round arc-shaped bottles. Labeling often encounters problems such as warping, wrinkling and peeling.
Instiker's 80μm white PE label material uses a special water-based adhesive formula. The base material is soft and pliable, with strong extensibility, and can closely adhere to various special-shaped curved surfaces, perfectly suitable for labeling of facial cleansers, body washes, skin care products and cosmetics tubes.
2. Food and Beverage and Fresh Produce Industry
For food packaging, fresh produce cold chain, and beverage bottle bodies, the requirements for moisture-proof, low-temperature resistance, and corrosion resistance of labels are extremely high.
PE label are non-toxic and odorless, food-grade safe and compliant. They have excellent low-temperature resistance and can be adapted for cold storage and refrigerated transportation scenarios. They will not become hard, crack, or peel off in low-temperature environments.
3. Industrial Chemicals and Logistics Warehousing Industry
Chemical reagents, industrial raw materials, and warehousing turnover products require acid and alkali resistant, corrosion-resistant, and wear-resistant identification labels.
PE label have extremely strong chemical stability and do not react with acids, alkalis, or weak corrosive reagents. They can be adapted for use on chemical barrels, reagent bottles, and industrial equipment identification.
4. Medical Devices and Daily Products Industry
Medical consumables, flexible catheters, and daily plastic products are mostly of flexible and curved structures. PE label have excellent flexibility, high adhesion, and no harmful substances are released, meeting medical safety standards.
5. Outdoor and architectural auxiliary signs
The modified weather-resistant PE label have excellent resistance to UV rays, aging, and temperature variations. They can withstand outdoor conditions such as sun exposure, rain, and temperature fluctuations, and are not prone to fading or cracking.
III. Analysis of Real Cases
Case One: Project for Adapting Food Cold Chain Storage Labels
Challenge
In the transportation process of a certain fresh food processing enterprise in Guangdong, the labels frequently experienced problems such as peeling, cracking, and blurred writing. The traceability identification became invalid, resulting in disorder in storage and sorting, and frequent complaints from customers after sales.
Solution
Customized low-temperature-specific PE label materials for Instiker
Result
It has extremely strong low-temperature resistance. Even in extremely low temperature environments, it does not become hard or crack. The glue uses a special low-temperature-resistant formula, ensuring stable adhesion and no failure due to low temperatures.
Case 2: Project for Corrosion Resistance Marking of Industrial Chemical Tanks
Challenge
A chemical raw material manufacturing enterprise has its industrial raw material barrels stored in open-air warehouses and damp workshops. The original paper and ordinary plastic labels are prone to corrosion by acid and alkali fumes as well as rainwater, resulting in label detachment and loss of information.
Solution
Use the anti-corrosion PE label material from Instiker
Result
Resistant to weak acids and alkalis, water vapor, and dust erosion, resistant to wear and aging. The outdoor storage period can reach more than 2 years. The label has clear writing and is firmly attached.
IV. Frequently Asked Questions Answered
Q: Compared to paper label, what are the advantages of PE labels?
A: The PE label has advantages that the paper label does not have, such as waterproofing, oil resistance, moisture resistance, corrosion resistance, resistance to stretching, and resistance to cracking.
