Industry Overview

Fresh and cold chain products have special requirements for labels—low temperature resistance (-18°C to -40°C frozen environment), water resistance (thawing condensation), and oil resistance (meat grease). Ordinary adhesive labels lose more than 50% of their stickiness in frozen environments, and condensation can contaminate paper labels, making information unreadable. Fresh product labels also need to comply with GB 7718 for product information labeling, and support piece-by-piece printing of variable production dates and batch numbers.

Industry Status

The fresh and cold chain market continues to grow, with continuously improving cold chain logistics infrastructure. Fresh products require temperature control from origin to table, and labels as information carriers must adapt to low-temperature, high-humidity environments. The State Administration for Market Regulation's requirements for fresh food label information are becoming increasingly stringent year by year—origin traceability, production date labeling, and storage condition descriptions are all regulatory priorities.

Product Characteristics

Fresh and cold chain products include frozen meat, seafood and aquatic products, frozen dim sum, low-temperature dairy products, chilled poultry, prepared dishes, etc. The common characteristics of these products are: they need to be stored and transported in low-temperature environments (-18°C to 4°C), and product surfaces are prone to condensation or oil seepage. Labels need to maintain stickiness in the following environments: freezer -40°C, cold chain transport vehicle 0-4°C, and thawing area at room temperature (temperature differences cause condensation).

Channel Characteristics

Main channels for fresh and cold chain products include: supermarket freezers (traditional retail 50%), fresh e-commerce platforms (Missfresh/Hema/Dingdong Maicai 30%), community group buying (10%), and catering supply chains (10%). Supermarket channels require labels to display product information on the front for consumer selection; e-commerce channel labels need to include space for express shipping label attachment; catering supply chains need batch traceability codes. The three channels correspond to different label formats and labeling positions.

Packaging Characteristics

Mainstream packaging solutions for fresh and cold chain products are: inner packaging (vacuum bags/tray + cling film) + outer packaging (foam box/EPP insulated box). Labels are mainly affixed to: the surface of heat-shrink film packaging bags (frozen meat), the top of laminated paper boxes (frozen dim sum), the seal of vacuum bags (seafood and aquatic products), and the outside of insulated boxes (logistics labels). The label face material needs to be selected based on the adhesive surface—smooth surface (laminated bags/shrink film) or rough surface (kraft paper boxes/foam boxes), with different requirements for adhesives on different surfaces.

Regulatory Requirements

Fresh and cold chain food labels must comply with GB 7718 General Rules for Prepackaged Food Labeling. Labeled content: food name, ingredient list, net content, producer and address, production date and shelf life, storage conditions, food production license number, and product standard code. Cold chain products specifically need to label storage conditions such as "frozen storage" and "store below -18°C". Origin traceability information must include: raw material origin, processing location, and packaging location. Fresh e-commerce also needs to label distribution temperature zones (frozen/chilled/room temperature).

Development Trends

Fresh product labels are transitioning from "basic information carriers" to "intelligent traceability portals". Variable QR code labels are becoming increasingly popular—consumers can scan the code to view the entire cold chain temperature records, origin traceability information, and testing reports. RFID temperature-sensing labels are beginning to be applied to high-end fresh products (imported steak/seafood), enabling real-time monitoring of temperature changes throughout the transportation chain. In terms of materials, the application of degradable bio-based label materials in the fresh product field is growing, with some leading brands already requiring the use of eco-friendly labels.

⚠️ What packaging challenges does your industry face?

  • ❌ Label detachment in low temperature environments The acrylic adhesive in ordinary self-adhesive labels has reduced molecular activity at low temperatures, resulting in a significant decrease in adhesion. Frozen products undergo multiple temperature changes from factory to retail terminal (-40°C→-18°C→4°C), with each temperature change challenging adhesive performance；Label detachment violates GB 7718 information integrity requirements and may result in removal penalties. Consumer complaint rates increase, and brand reputation is damaged. Some retailers have assessment indicators for label detachment rate (typically requiring <1%)
  • ❌ Condensation causes label blurring and damage Ordinary coated paper/thermal paper labels are not waterproof. The temperature difference on the surface of frozen products can reach over 40°C (-18°C→25°C), and moisture in the air condenses into water droplets on the label surface and is absorbed by the paper；Consumers cannot read production date and shelf life, and return rates increase. Retailers need to manually relabel products, increasing operational costs. Thermal paper labels become completely blank after absorbing moisture
  • ❌ Meat grease contaminates label surface During transportation and sales, grease and blood in fresh meat packaging bags seep out to the package surface due to compression. If the label is positioned in the oil-seeping area, oil stains cover the label surface making information unreadable；Once QR codes are contaminated, consumers cannot scan them to query traceability information. Unscannable barcodes affect checkout efficiency. Some retailers require secondary lamination protection for labels, increasing costs
  • ❌ Low efficiency in piece-by-piece production date printing Fresh products are made-to-order, with different times and batch numbers for each batch. Pre-printed label inventory can only print fixed information and cannot change in real-time with the production rhythm. Traditional inkjet printers have unstable ink flow in low-temperature workshops, resulting in unreadable barcodes；Inkjet printing efficiency bottlenecks limit overall production line speed. Unreadable barcodes break the traceability chain, and accurate recalls cannot be performed if food safety issues arise. Mistakenly printed production dates violate GB 7718
  • ❌ Difficult unified management of multi-temperature zone cold chain delivery labels Different temperature zones have different requirements for label temperature resistance grades. The frozen zone requires low-temperature adhesive + synthetic paper, the chilled zone can use laminated coated paper, and there are more material options for the ambient zone. Multiple materials mean multiple inventory management and procurement processes；Label material procurement has many categories and complex inventory. Products with labels from the wrong temperature zone may experience problems throughout the entire cold chain

Low-Temperature Resistant Label Strategy

Scenario:Frozen meat, quick-frozen pastries, ice cream and other products need to maintain label adhesion in environments from -18°C to -40°C
Approach:Use frozen-grade adhesive materials (low-temperature adhesive + synthetic paper/PE face stock) to maintain adhesion without falling off in -40°C environments. The face stock uses synthetic paper (YUPO) or PE film, which is waterproof, oil-resistant, and tear-resistant. Combined with frozen-grade adhesive to ensure peel strength ≥5N/25mm in -18°C environments
Packaging Plan
Structure:Frozen-Grade Adhesive Label
Material:Synthetic Paper (YUPO) / PE Film
Grammage:-
Process:Digital Printing + Lamination + Frozen-Grade Adhesive
Label:Frozen Low-Temperature Resistant Label
Label Details:Resistant to -40°C low temperatures, waterproof and oil-resistant, passes -40°C to 25°C cyclic temperature change test
Decision Reason
Why This:Synthetic paper (YUPO) labels maintain flexibility and do not become brittle at -40°C; PE film labels do not absorb water or curl in condensation environments. The peel strength of frozen-grade adhesive at low temperatures is more than 3 times that of ordinary adhesives, ensuring no falling off throughout the entire cold chain
Suitable For:Quick-frozen food factories, frozen meat suppliers, ice cream manufacturers, frozen seafood export companies
Not Suitable For:Room-temperature distribution products (high cost), dry goods that do not require frozen storage
Expected Impact:The cost per frozen-grade label is 40-60% higher than ordinary labels, but the losses from returns and fines due to label falling off far exceed the material price difference；Digital printing delivers samples in 3 days, delivery in 5-7 days. Variable data inkjet printing and printing are completed simultaneously；Supports production-to-order, no need to pre-print large inventory. Frozen-grade label material stocking cycle is about 5 days；After confirming product stability, it can be converted to a combined digital + flexographic hybrid printing solution to further optimize costs
✅

Waterproof and Oil-Resistant Label Strategy

Scenario:Surface oils and condensation on fresh meat and seafood easily contaminate labels
Approach:Lamination protection + synthetic paper substrate solution. The face stock uses synthetic paper or PE film, combined with lamination process (matte film/glossy film) to form a physical protective layer that blocks moisture and oil penetration. The ink layer is protected by lamination, preventing fading and smudging
Packaging Plan
Structure:Waterproof and Oil-Resistant Adhesive Label
Material:Synthetic Paper (Laminated)
Grammage:-
Process:Digital Printing + Matte Lamination + Water-Resistant Adhesive
Label:Waterproof and Oil-Resistant Label
Label Details:Surface lamination protects the printed surface; synthetic paper substrate does not absorb water or deform; water-resistant adhesive maintains adhesion on wet surfaces
Decision Reason
Why This:The lamination layer forms a physical barrier, preventing oil stains and water droplets from contacting the printed surface. Synthetic paper itself does not absorb water, so even surface condensation will not cause blurred text. The adhesion retention of water-resistant adhesive on wet surfaces is twice that of ordinary adhesives
Suitable For:Fresh meat processing companies, chilled poultry suppliers, prepared food manufacturers, seafood and aquatic product companies
Not Suitable For:Products with extremely oily packaging surfaces (such as pure oil meat products, requiring an oil-free labeling area on the packaging)
Expected Impact:The laminated + synthetic paper solution costs about 0.2-0.5 yuan per label, which is 0.1-0.2 yuan higher than ordinary unlaminated labels, but avoids the huge losses from returns and re-labeling；Sample confirmation in 3 days, delivery in 5-7 days；Production-to-order, minimum order of 500 sets, avoiding label expiration and waste；Seamless material switching (e.g., upgrade to PE film face stock if higher waterproof grade is required)
✅

Variable Data Traceability Strategy

Scenario:Each product requires independent variable production dates, batch numbers, and traceability codes
Approach:Use digital printing + variable data inkjet coding to print product information (product name/net weight), batch information (production date/shelf life/batch number), and traceability information (traceability code/QR code) in one pass. Supports integration with ERP systems for batch generation of variable data
Packaging Plan
Structure:Variable Data Adhesive Label
Material:Synthetic Paper or Laminated Coated Paper (selected by temperature zone)
Grammage:-
Process:Digital Printing (fixed information) + Variable Data Inkjet Coding (batch information)
Label:Variable Data Traceability Label
Label Details:Fixed information: Logo/product name/ingredients/specifications; Variable information: production date/shelf life/batch number/traceability code
Decision Reason
Why This:The digital printing + inkjet coding combination is completed in one process, requiring no secondary processing. Variable data inkjet coding has high precision and fast speed, printing 200+ pieces per minute. Direct integration with customer ERP systems automatically retrieves batch information, reducing manual entry errors
Suitable For:Large quick-frozen food factories, fresh food processing centers, central kitchens, export food companies
Not Suitable For:Very small batch hand-packed products (less flexible than ready-made label printers)
Expected Impact:No need for pre-printed label inventory, zero switching cost for batch changes. Overall cost reduced by 15-20% compared to pre-printing + thermal transfer solutions；From data confirmation to finished printing in 3-5 days, rush orders supported；Production-to-order with zero inventory. Supports data changes within 2 hours (batch number/date/price changes)；From 1 piece to 100,000 pieces per batch, flexibly adapting to production rhythms. Supports integration with traceability platforms and e-commerce APIs
✅

Full Temperature Zone Unified Label Management Strategy

Scenario:Covers three temperature zones: frozen, refrigerated, and room temperature, requiring unified label procurement standards
Approach:Establish a label standard of "unified face stock + graded adhesives." Frozen zone uses PE film + frozen adhesive, refrigerated zone uses synthetic paper + water-resistant adhesive, room temperature zone uses laminated coated paper + standard adhesive. Face stock categories unified to 2-3 types, adhesives graded by temperature zone, reducing inventory SKUs
Packaging Plan
Structure:Graded Temperature Control Label System
Material:Frozen zone: PE film; Refrigerated zone: synthetic paper; Room temperature zone: laminated coated paper
Grammage:-
Process:Digital Printing + Adhesive Selection by Temperature Zone
Label:Graded Temperature Control Label
Label Details:Unified brand visual design, with corresponding materials and adhesives selected by temperature zone
Decision Reason
Why This:Face stock categories reduced to 3 or fewer, simplifying procurement and inventory management. Unified visual design maintains brand consistency; after standardizing the logic of selecting materials by temperature zone, the probability of mislabeling is greatly reduced
Suitable For:Full temperature zone fresh food brands, multi-category fresh food suppliers, cold chain logistics companies
Not Suitable For:Single temperature zone specialized companies (do not require graded solutions)
Expected Impact:Concentrated unified procurement leads to lower prices, with overall label procurement costs reduced by 10-15%. Reduced inventory SKUs lead to lower management costs；Common materials are well-stocked, production starts immediately upon order. After grading, delivery times for each temperature zone label are unified；Label material SKUs reduced by 70%, simplifying warehouse management. Material turnover cycle shortened；The unified brand visual system expands rapidly with new product lines; simply determine the temperature zone to determine the label solution

❓ FAQ

How long does the label on frozen meat stay attached?

Frozen-grade labels maintain adhesion for over 12 months at -18°C, and have passed 10 cycles of temperature variation testing from -40°C to 25°C without detachment.

What is the minimum order quantity for fresh food labels?

Minimum order is 1 roll of self-adhesive labels (approximately 500-1000 sheets/roll), suitable for small-batch, multi-variety fresh product label needs.

Can the production date and batch number be different for each item?

Yes. Digital variable data printing supports item-by-item independent coding. The production date, shelf life, batch number, and traceability code can all be unique for each product. ERP system integration for automatic data retrieval is supported.

What mandatory labeling information is required for fresh food labels?

Per GB 7718 requirements: food name, ingredient list, net content, producer and address, production date and shelf life, storage conditions, and food production license number. Cold chain products must indicate the temperature zone.

Will the label stick to vacuum packaging surfaces?

We recommend a synthetic paper + strong adhesive solution. Vacuum packaging surfaces are smooth, and standard self-adhesive labels lack sufficient adhesion. Synthetic paper labels use optimized adhesive, achieving peel strength of ≥8N/25mm on smooth vacuum bag surfaces.

Do products in different temperature zones require different labels?

We recommend tiered management by temperature zone. Use frozen-grade (-40°C) for frozen zones, water-resistant grade for refrigerated zones, and standard grade for ambient temperature zones. Lexiang can provide unified visual design with only materials and adhesives adjusted by temperature zone, maintaining brand consistency.
