How to Choose the Right Label Material? Guide to Label Material Selection for Different Products

Label material errors double subsequent costs

Labels are the outer garment of a product. Choosing the wrong material can cause labels to lift, fade, fall off, and even affect product compliance. Proper material selection requires comprehensive consideration of four dimensions: product type, labeling environment, durability requirements, and budget. Below is a systematic selection method from requirements to materials.

Step 1: Determine product type and compliance requirements

Food labels require face material to comply with GB 4806 series food contact standards; PET and PP are common choices. Pharmaceutical labels need to meet drug supervision code traceability requirements and also consider specific sterilization environments (e.g., ethylene oxide sterilization). Electronic labels have requirements for temperature resistance and insulation; PET is the first choice. Daily chemical labels are mainly for brand display; coated paper or PP is sufficient. Export products also need to confirm whether the supply chain meets RoHS and REACH requirements.

Step 2: Assess the labeling environment

For normal temperature dry environments, coated paper with lamination is sufficient, low cost and good printing effect. For humid or freezing environments, synthetic paper/PET with freezer-grade or waterproof adhesive must be used. For long-term outdoor exposure, PET face material with permanent adhesive and lamination is needed to ensure weather resistance. For high-temperature environments (e.g., engine compartments), special high-temperature resistant materials (polyimide) are required. For low-temperature environments (below -20°C), freezer-grade synthetic paper and freezer-grade adhesive are needed.

Step 3: Determine durability requirements

For temporary labels (price tags, promotional stickers), removable adhesive can be used, leaving no residue when peeled off. For permanent identification (equipment nameplates, safety labels), PET face material with permanent adhesive and lamination is needed, durable for 3-5 years or more. Tamper-evident seals require frangible paper material that shatters upon removal and cannot be restored. Re-positionable labels (e.g., shipping labels) require re-positionable adhesive that maintains tack after repeated application.

Step 4: Match the budget

Coated paper has the lowest cost, suitable for high-volume, dry environments. PP offers good cost-performance, suitable for medium-requirement scenarios like daily chemical and food. PET has higher cost but the best overall performance, suitable for high-requirement scenarios like outdoor and electronics. Synthetic paper has the highest cost, used for extreme environments like freezing and outdoor. The printing method also affects total cost: digital printing has no plate fees, more flexible for small batches; offset or flexographic printing for large volumes can reduce unit price.

Scenario recommendation quick reference

For beverage bottle labels, PP face material with permanent adhesive is recommended, cost-controlled with good labeling effect. For cosmetic bottles, PET transparent labels with hot stamping or partial UV process are suggested to enhance texture. Courier waybills use thermal paper for direct printing. Frozen food labels require synthetic paper with freezer-grade adhesive. Outdoor equipment identification uses PET with permanent adhesive and lamination to ensure 5 years of no fading.
