Cold Storage Special Tape: Core Features, Selection Guide & Notes

I. Core Features of Cold Storage Special Tape (Key Properties for Low-Temperature Environments)

Cold storage special tape (low-temperature tape) is a specialized adhesive tape designed for low-temperature and high-humidity scenarios such as cold storage warehouses and cold chain logistics. Its core features revolve around “low-temperature adaptability, adhesion stability, and weather resistance,” detailed as follows:

1. Super Strong Low-Temperature Adhesion, No PeelingAdopts low-temperature-specific pressure-sensitive adhesives (e.g., special acrylic adhesive, rubber-based low-temperature adhesive), maintaining strong initial tack and holding power in environments ranging from -40℃ to 0℃. It won’t easily curl, peel, or exude adhesive after application (unlike regular tape, whose adhesive layer hardens and loses stickiness at low temperatures).Offers excellent conformability, adhering tightly to surfaces like low-temperature refrigerated boxes, corrugated cartons, and metal packaging—even with slight condensation on the adherend surface.
2. Low-Temperature & High-Humidity Resistance, Stable PerformanceThe tape substrate (mostly BOPP, PET, or special film) undergoes low-temperature resistance treatment, remaining flexible without brittleness or stiffness in extreme low temperatures for easy manual or machine carton sealing.Both the adhesive layer and substrate feature moisture resistance, withstanding high humidity in cold storage to prevent reduced adhesion or tape delamination due to moisture absorption.
3. High Tensile Strength & Tear ResistanceThe substrate is typically thicker than regular carton sealing tape (≥50μm) or made of reinforced materials, boasting a tensile strength of ≥20N/25mm and strong tear resistance. It can withstand vibrations and stacking pressure during cold chain transportation, preventing package damage.
4. Environmentally Friendly & Safe, Suitable for Food Cold ChainComplies with food contact standards (e.g., FDA, GB 4806). The adhesive layer is odorless with no migration of harmful substances, making it suitable for direct use in food packaging (e.g., sealing outer cartons of fresh and frozen foods) without contaminating the products.
5. Easy Tear (Optional)Some products are designed for “manual easy tearing,” allowing quick separation without scissors. Ideal for fast carton sealing in cold storage, improving work efficiency.

II. Selection Guide for Cold Storage Special Tape (5 Key Dimensions)

1. Clarify Operating Temperature Range (Core Premise)First confirm the actual cold storage temperature: regular cold storage (-18℃~0℃), deep cold storage (-40℃~-18℃), or room-temperature cold chain transportation (0℃~10℃).Choose tape with a corresponding temperature resistance rating: regular low-temperature tape for above -18℃, and deep cold-specific tape labeled “withstands -40℃” to avoid adhesion failure due to temperature mismatch.
2. Prioritize Adhesive Layer Type (Determines Adhesion Stability)Prefer acrylic low-temperature adhesive: Excellent low-temperature resistance, long holding time, and anti-aging properties—suitable for long-term cold storage (e.g., frozen food packaging stored for over 3 months).Secondary choice: Rubber-based low-temperature adhesive: Strong initial tack and flexibility—ideal for short-term cold chain transportation (e.g., turnover packaging within 1 month), but slightly inferior to acrylic adhesive in anti-aging performance.Avoid: Regular hot-melt adhesive or water-based adhesive tape, which hardens and loses stickiness at low temperatures—never suitable for cold storage scenarios.
3. Pay Attention to Substrate Material & Thickness (Affects Tensile/Tear Resistance)Substrate options:

• BOPP substrate: Moderate cost and high cost-effectiveness, suitable for regular carton sealing.
• PET substrate: Superior low-temperature resistance and tensile strength, ideal for deep cold environments or heavy packaging.
• Special non-woven substrate: Exceptional flexibility, suitable for irregular packaging surfaces.Thickness reference: 50~60μm for regular cold storage; 60~80μm thickened substrate for deep cold or heavy packaging to prevent brittleness at low temperatures.

4. Align with Usage Scenarios & AdherendsCarton sealing: Select wide-width (45~60mm) tape with high adhesion to ensure tight sealing, preventing cold air leakage and moisture ingress.Label application: Choose thin, easily die-cut low-temperature tape paired with waterproof label paper to avoid label peeling.Adherend surfaces:

• Corrugated cartons: Tape with strong initial tack.
• Metal/plastic packaging: Acrylic adhesive with good material compatibility to avoid corrosion or peeling.

5. Verify Environmental & Safety Standards (Mandatory for Food Cold Chain)For food packaging, ensure the tape complies with:

• FDA 21 CFR Part 175.105 (U.S. standard) or GB 4806.8 (Chinese food contact material standard).
• Odorless and free of heavy metal exceeding limits.Avoid tape with recycled substrates or inferior adhesive layers to prevent migration of harmful substances to food.

6. Reference Brands & Conduct Practical Tests (Reduce Risks)Prioritize brands specializing in specialized tapes (e.g., 3M, Tesa, Yongfeng Packaging). Request low-temperature adhesion test reports (e.g., holding power test, peel strength test) from manufacturers for quality assurance.Small-batch trial: Purchase samples first, conduct adhesion tests in actual cold storage environments, and observe adhesion status (curling, peeling) after 24 hours and 72 hours before bulk purchasing.

III. Additional Notes

Storage conditions: Store the tape in a room-temperature, dry environment (avoid pre-exposure to low temperatures). Remove it 1~2 hours before use to acclimate to the environment, enhancing adhesion 效果.

Operation specifications: Ensure the adherend surface is clean, free of condensation and oil. Press evenly to avoid air bubbles, improving adhesion stability.

Cost balance: Deep cold-specific tape and PET substrate tape have higher costs. For regular cold storage and short-term use, BOPP substrate acrylic low-temperature tape offers a balance of cost-effectiveness and practicality.

By considering the above dimensions, you can accurately select cold storage-specific tape, avoiding package failure and cargo damage caused by improper product selection.
