Client Background:
A food brand's new product series, including two categories of baked snacks and candies, with 6 flavors under each category, totaling 12 SKUs. The client's initial new product launch order volume was small (approximately 40 sets per SKU), but with expectations of continuous production and reorders. Terminal shelf display environment involves normal temperature display areas, with some products (like dried fruit, baked gift sets) requiring temporary display in refrigerated cabinets. The client faced three challenges with the original label solution: refrigerated wrinkling, high multi-SKU sampling costs, and slow revision response.
💬 Customer Needs
A food brand upgraded packaging labels for new product launches. Original solution problems focused on three aspects:
First, the original labels used standard coated paper + thin lamination, which after 3 weeks in refrigerated display (around 4-8°C) on glass bottles showed wrinkling and edge lifting, requiring frequent re-labeling and seriously affecting new product shelf image.
Second, 12 SKUs (2 categories of baked snacks + 6 flavors × 2 series) were previously sampled at different printing houses, with sampling fees of 300-500 yuan per style and 5-7 days per sample cycle, resulting in high communication and revision costs.
Third, the original ink system lacked food safety compliance documentation, failing to enter qualification checklists for food packaging in some supermarkets.
Project Challenges:
✓ Multi-SKU small batch: 12 styles × approximately 40 sets/style, no need for mass production plates
✓ Refrigeration environment adaptation: Labels need stable adhesion on glass bottle surfaces at 4-8°C for over 4 weeks
✓ Food-grade compliance: Ink and adhesive need quotable food contact standards
✓ Quick revision: Post-launch flavor switches require rapid response
💡 Solution
Provided packaging adhesive label customization for 12 new products of a food enterprise: Using coated paper face material (80g) + food-grade four-color ink + 25μ glossy film lamination + permanent acrylic adhesive solution, with 40 sets minimum per SKU. Combined 12 labels into one printing batch for unified sampling and batch delivery, solving the problems of refrigerated wrinkling and high multi-SKU sampling costs.
(Selection Analysis:)
Why coated paper labels?
Coated paper has smooth surface and high printing color reproduction, suitable for food visual design needs. The client's existing product line has always used coated paper system, continuing with the same face material reduces equipment adjustment and process validation costs. Food shelf displays are typically in normal temperature display areas, without rigid industrial weather resistance requirements, coated paper can meet usage conditions.
Why not continue with original thin lamination?
Original lamination thickness was insufficient and did not cover edges, allowing moisture to seep into the lamination layer from cut edges, causing adhesive layer failure after repeated moisture absorption in cold environments. Upgrading lamination thickness to 25μ and fully covering die-cut edges creates a continuous protective layer, preventing moisture intrusion into the adhesive layer.
Why not synthetic paper?
Synthetic paper has plastic film texture, not matching the 'natural, handmade' visual tone of baked snacks. Synthetic paper is typically recommended for variable information labels or industrial scenarios, which is too cold for food brand tone, and unit price is about 30% higher than coated paper, uneconomical for small batch new products.
Why not PVC labels?
PVC has strong oil and moisture resistance, mainly used in industrial equipment and outdoor scenarios. Food products with short shelf life (6-12 months) typically do not require industrial-grade durability. PVC is more suitable for solving harsh environment problems like production workshop lubricants and freezers, over-spec for food labels.
Glossy film vs Matte film selection:
Glossy film has high light transmittance, better presenting four-color printing color saturation, suitable for shelf display products (candies, baked snacks). Matte film has more delicate diffuse reflection texture, mainly used for premium gift boxes, cosmetics, book covers and other scenes requiring understated texture. The client wanted new products to have visual impact on shelves, so glossy film was selected.
Adhesive selection:
Permanent acrylic adhesive is not easily torn off after application, meeting food packaging expectations of 'stick and stay'. Food-grade adhesive has good initial tack and holding power on glass, PET bottles, and plastic boxes. The client's actual working conditions involve refrigerated display, so adhesive needs low temperature resistance. Permanent acrylic adhesive maintains holding power in low temperature environments, suitable for this case.
(Production Implementation and Quality Control:)
① Client finalized 12 designs centralized proofreading → ② Digital sampling (use digital printer to output 1 set of physical samples for color and material feel confirmation) → ③ Client confirmation signature → ④ Four-color printing combining 12 contents at once (printing color sequence, ink volume, temperature and humidity controlled according to coated paper standards) → ⑤ 25μ glossy film lamination (lamination temperature and pressure set according to adhesive activation range, avoiding premature adhesive activation due to high temperature) → ⑥ Die cutting (12 sets of die-cut blades combined off-machine, including complete waste removal) → ⑦ Inspection (inspect actual adhesion effect, including simulated refrigeration environment 4-8°C static test) → ⑧ Rewinding/sheet separation → ⑨ Packaging and shipment
Quality control points: Ink uses soy ink system meeting GB 4806.7 indirect food contact material requirements; lamination temperature real-time monitoring; manual full inspection of edge burrs after die cutting; batch retention samples before shipment for subsequent traceability.
