1. Basic material
PP
Features: Lightweight, high temperature resistant (-20 ℃~120 ℃), chemical corrosion resistant, non-toxic and environmentally friendly
Application: Food trays, daily necessities packaging, industrial parts lining.
PETG
Features: high transparency, strong impact resistance, easy to heat form, environmentally friendly and recyclable.
Application: Cosmetics packaging, medical equipment trays, electronic product blister boxes.
PS
Characteristics: High rigidity, low cost, easy to print, but poor temperature resistance (<70 ℃).
Application: Toy packaging, disposable tableware, stationery inner tray.
PVC
Characteristics: Good flexibility, strong flame retardancy, but prone to releasing chlorine gas at high temperatures
Application: Electronic product sheath, tool box lining.
Features: APET has high transparency, CPET is resistant to high temperatures (can be microwave heated).
Application: Baking food tray, frozen food packaging.
2. Expansion of functional materials
Anti static material: added with anti-static agent, with a surface resistance value of 10 ^ 6~10 ^ 9 Ω, used for electronic component trays.
Antibacterial material: Adding silver ions or organic antibacterial agents, suitable for medical and food packaging.
Biodegradable materials: PLA or starch based materials, in compliance with environmental regulations.
2、 Color and surface effect customization
1. Basic color
Monochrome sheet: white, black, gold, silver, red, blue, etc. (mixed with color masterbatch).
Transparent/Translucent: PETG and APET can provide full transparency or matte effect.
2. Special effects
Pearlescent/Metallic Texture: Add pearl powder or metallic powder to enhance the appearance grade (such as gold or rose gold).
Texture surface: Embossing treatment (frosted, brushed, leather grain) enhances slip resistance or aesthetics.
3、 Customized demand response plan
1. Size and structural design
Thickness range: 0.2mm~3.0mm (depending on load-bearing requirements, such as commonly used 1.5~2.5mm for food trays).
Mold development:
Mold material: aluminum alloy (high precision, long life), resin (small batch trial production).
Design support: Provide 3D drawing optimization suggestions to ensure the feasibility of vacuum forming (such as draft angle, reinforcement rib layout).
2. Function enhancement
Strengthen compressive strength: Enhance load-bearing capacity through structural design (honeycomb bottom support) or increasing thickness.
Sealing requirement: Use a cover material (such as PET/AL composite film) to achieve airtight packaging (for electronic moisture prevention).
Stacking design: snap on or nested structure for easy transportation and storage.
3. Certification and Compliance
Food grade certification: Provide FDA and EU 10/2011 testing reports for PP and PETG materials.
Environmental certification: RoHS, REACH, biodegradable material certification
Industry standard: The anti-static tray complies with the ESD S20.20 standard.
4、 Production Process and Quality Control
1. Production process
Requirement confirmation: The customer provides samples or drawings, specifying the material, color, and quantity.
Mold making: 3-15 days (depending on complexity).
Sheet extrusion: Production of customized color and thickness sheets.
Vacuum forming: Fully automatic vacuum forming machine for heating, forming, and cutting.
Post processing: punching, folding, printing, quality inspection.
2. Quality inspection standards
Appearance inspection: No bubbles, scratches, or deformation.
Dimensional tolerance: ± 0.5mm
Functional testing: Anti static tray surface resistance test, food grade material migration test.
5、 Customer cooperation case reference
Food industry: Customized gold pearl PP trays (thickness 2.0mm) for chain baking brands, supporting microwave heating, with a monthly production capacity of 500000 pieces.
Electronics industry: produces anti-static black PS trays with a surface resistance of 10 ^ 8 Ω, used for packaging semiconductor components.
Medical industry: Transparent PETG sterilization tray, compliant with ISO 13485 medical device packaging standards.
6、 Service advantages
Quick sampling: Provide sample confirmation within 3-7 days.
Flexible minimum order quantity: from small-scale trial production (starting from 1000 pieces) to large-scale production support.
Full tracking: Provide one-on-one customer service from design to delivery.
