Build specification
Behind every Packlic box is one of six carefully sourced substrates: Kraft Board, Corrugated Board, Coated Art Board (C1S), Rigid Greyboard, Solid Bleached Sulfate (SBS), and Metallic Board. The lineup covers everything a brand might need — recyclable kraft for artisan and sustainability-led ranges, thick greyboard for luxury rigid boxes, and clean virgin-fibre SBS for cosmetics, pharma, and premium retail. Whether the goal is a budget-friendly corrugated mailer or the confident heft of a magnetic-closure rigid box, we specify FSC-certified stock built to perform on the shelf, in transit, and when the customer lifts the lid.
A considered finish is the difference between packaging that is seen and packaging that sticks in memory. Our menu runs from soft-touch matte and high-gloss lamination to silk lamination, spot UV, gold and silver foil stamping, embossing, debossing, and aqueous coating. Spot UV adds a gloss-on-matte contrast that guides attention to your logo, and soft-touch lamination gives rigid boxes a velvety feel that reads as quality on contact. Foil stamped onto SBS or coated art paper lands the crisp metallic detail luxury cosmetic, fragrance, and gifting brands use to justify premium prices and fuel share-worthy unboxings.
The feel of your packaging and its durability in transit both trace back to paper weight, which we offer from lightweight 8pt up to heavyweight 28pt on the point system US and UK packaging suppliers use. Lightweight 8pt–12pt is well suited to folding cartons and high-volume retail boxes. Mid-range 14pt–18pt is the workhorse of retail packaging, balancing protection against economical shipping. Heavyweight 20pt–28pt supplies the rigid, substantial character essential to luxury gift boxes, rigid set-up boxes, and premium cosmetic packaging, where the weight of the box communicates quality the instant it is picked up.
Custom Mylar Envelopes for Specialty Mailing Programs
Custom mylar envelopes serve a specialty mailing packaging category where document protection programs, electronics shipping operations, tamper-evident mailing programs, and specialty mailing applications all rely on packaging engineered for the specific moisture protection and tamper-evident requirements of mylar envelope shipping applications. The mylar envelope category combines functional barrier protection requirements with branded mailing presentation supporting both commercial document distribution and consumer ecommerce shipping where moisture damage and tampering during shipping carrier handling represent significant operational risks.
Heat-Seal Envelope Construction
Construction quality defines mylar envelope performance significantly because envelope reliability directly affects shipping protection across delivery cycles spanning days to weeks of carrier handling. Our mylar envelopes use 4-layer to 5-layer laminate construction including PET outer layer for printability, aluminum foil barrier blocking moisture migration, polyethylene inner layer for heat-seal compatibility, and additional barrier layers preventing contents compromise. Heat-seal flap closures create tamper-evident seals showing visible damage if opened during shipping providing security assurance important for document and sensitive contents shipping applications.
- 4-layer to 5-layer laminate construction
- PET outer for printability and durability
- Aluminum foil prevents moisture damage
- Heat-seal flap creates tamper evidence
Specialty Application Selection
Application choice depends on contents type and shipping requirements across diverse mylar envelope markets. Standard heat-seal envelopes work for cost-efficient document shipping protection at commercial mailing operations. Anti-static mylar envelopes provide electronics shipping protection preventing electrostatic discharge damage during carrier handling that compromises sensitive electronic components. Security mailing envelopes with tamper-evident closures serve legal document distribution and high-value contents shipping. Medical sample shipping envelopes accommodate biological sample distribution supporting laboratory and clinical testing programs requiring temperature stability.

- Anti-static for electronics protection
- Security envelopes for legal documents
- Medical sample shipping envelopes
Custom Branding for Commercial Mailing
Branding on mylar envelopes drives recognition across commercial mailing operations where envelopes deliver brand identity at customer dropoff. The exterior surface accepts vibrant CMYK offset printing for company logos, return addresses, contact information, and marketing messaging that connects recipients to sender brand identity. PMS spot color printing locks signature corporate colors across multiple production runs. Window cutout options accommodate addressing requirements for mailing applications. Color-coded envelope programs across product categories simplify visual identification during commercial mailing operations supporting distribution efficiency.
Tamper-Evident Security Features
Tamper-evident security features matter significantly for mylar envelopes shipping legal documents, medical samples, and high-value contents requiring proof of unopened shipping integrity. Heat-seal flap construction provides clear visual evidence of envelope integrity supporting recipient confidence in contents safety. Once heat-sealed, envelopes cannot be reopened without visible damage to seal evidence providing tamper-evident assurance important for legal document distribution and sensitive medical sample shipping. Custom security features including void patterns and breakaway closures support specialty high-security shipping applications.
