Environmental Sustainability: Made from virgin wood pulp or recycled paper, blister paper is biodegradable and recyclable, aligning with global "plastic reduction" trends, including the EU's Packaging Waste Directive and China's Plastic Ban Policy.
Functional Properties: Surface coatings endow blister paper with features like non-stick, waterproofing, high-temperature resistance (up to 120°C+), and high barrier performance (moisture and grease resistance), catering to diverse application requirements.
Processing Compatibility: It exhibits excellent heat-sealing adhesion with blister materials such as PVC, PET, and PP, making it suitable for thermoforming and blister packaging processes.
Printing Capabilities: The smooth surface supports high-precision offset printing, flexographic printing, hot stamping, and other printing techniques, enhancing packaging aesthetics.
Core Application Areas and Scenarios
(1) Food and Catering Packaging
1. Bakery and Pastry Packaging
Application Scenarios: Muffin cups, cake bases, donut blister trays, baking paper trays
Product Advantages:
Silicone-coated blister paper ensures excellent non-stick properties, enabling clean cake release without sticking.
High-temperature resistant coatings can withstand 180°C baking temperatures, allowing direct contact with ovens.
Complies with food contact safety standards (e.g., FDA 21 CFR 176.170, GB 4806.8), ensuring no migration risks.
Case Study: McDonald's muffin cake trays use laminated blister paper, balancing oil resistance and thermoforming stability.
2. Takeaway and Ready-to-Eat Food
Application Scenarios: Burger wraps, fried chicken oil-absorbing trays, salad box liners, rice ball blister packaging
Product Advantages:
Greaseproof layers effectively absorb food oils, maintaining packaging cleanliness.
Laminated blister paper's waterproofing prevents sauce leakage and external contamination.
Lightweight design reduces takeaway delivery costs, replacing some single-use plastic containers.
Technical Parameters: Grease permeability ≤ 5g/㎡·24h; water vapor transmission rate ≤ 15g/㎡·24h (38°C, 90%RH).
(2) Electronics and 3C Product Packaging
1. Precision Device Protection
Application Scenarios: Blister liners for smartphone chargers, earphone packaging, battery blister trays, PCB board trays
Product Advantages:
Anti-static coatings (surface resistance 10⁶ - 10¹⁰Ω) prevent electrostatic damage to electronic components.
**High-stiffness paperboard (300 - 400GSM) provides mechanical support, preventing deformation during transportation.
Combination of transparent PET blisters and white cardboard enables "windowed" packaging for product visibility.
Case Study: Apple AirPods Pro packaging uses blister paper liners, integrating cushioning protection with minimalist design.
2. Specialized Battery Packaging
Unique Requirements: Lithium battery packaging demands flame retardancy, moisture resistance, and insulation
Solutions:
Flame-retardant blister paper (compliant with UL 94 V-0 standard) suppresses flame spread.
Aluminum foil composite blister paper enhances moisture resistance and electromagnetic shielding.
Die-cutting technology customizes shapes for irregular batteries, ensuring secure positioning.
(3) Pharmaceutical and Medical Device Packaging
1. Pharmaceutical Blister Packaging
Application Scenarios: Liners for tablet/capsule blister packs, blister trays for medical catheters
Core Advantages:
Pharmaceutical-grade coated paper (certified by ISO 11607-1 for sterile packaging) withstands ethylene oxide or radiation sterilization.
Low-dust materials prevent product contamination, meeting GMP production standards.
Laser-scored tear lines facilitate patient access, improving usability.
Technical Standards: Dissolution tests comply with international pharmacopoeia requirements, such as USP <661> and EP 3.1.3.
2. Medical Device Packaging
Application Scenarios: Primary packaging for syringes, scalpels, and other sterile devices
Key Performance:
High-barrier materials (oxygen transmission rate ≤ 5cm³/㎡·24h) extend sterile shelf life.
Heat-sealed with Tyvek® film to create a complete sterile barrier.
Printable traceability information (batch numbers, sterilization dates) meets medical industry traceability requirements.
(4) Beauty and Personal Care Product Packaging
1. Cosmetic Packaging
Application Scenarios: Lipstick blister trays, powder compact liners, sample packaging for skincare products
Product Highlights:
Pearlescent or matte coated paper enhances packaging luxury, supporting high-end printing techniques like hot stamping and UV coating.
Non-stick coatings prevent product adhesion, maintaining integrity.
Lightweight design aligns with the beauty industry's "portable and elegant" trend, reducing transportation costs.
2. Wet Wipes and Hygiene Products
Special Applications: Wet wipe lids, packaging liners for sanitary napkins
Technical Requirements:
High wet tensile strength (≥ 30N/m) ensures durability in humid conditions.
Sealing coatings with tear lines enable repeated opening without leakage.
Environmentally friendly inks prevent chemical migration upon skin contact.
