Many customers assume packaging success depends on the outer appearance (outer box printing). In fact, it often hinges on the inner lining (liner structure).
An expensive piece of jewelry will rattle and get damaged during delivery if the liner is too soft. A delicate cake may go moldy when delivered if the liner is not breathable. The liner is the last line of defense for product safety. With 10 years of focus on paper packaging, Hanlong Crafts provides scientific physical protection instead of fancy fillers.
Three Core Functions of Liners
Please clarify your needs before choosing a liner:
| Function |
Core Pain Point |
Hanlong Liner Strategy |
| Fixation & Anti-movement |
Products shake and collide inside the box, causing damage or scratches |
Precision Snap-fit: Physically locks products in place using paper elasticity or high-precision slotting |
| Cushioning & Shock Absorption |
Violent courier delivery transfers impact directly to products |
Resilience & Energy Absorption: Uses high-density corrugated board or special sponge to absorb impact and protect fragile parts |
| Display & Aesthetics |
Products are buried in fillers, looking cheap |
Suspension / Support Design: Lifts products like exhibits for enhanced ceremonial sense |
Hanlong Engineer Tip:Thicker liners are not better. Over-thick liners squeeze products and bulge the box lid; too-thin liners fail to protect.
Hanlong’s standard: securely hold products without damaging the box shape.

Recommendations by Product
-
Jewelry / Watches (scratch-sensitive, luxury-focused)
Preferred: Flocked paper tray / EVA
Reason: Metal surfaces are vulnerable to friction; flocking physically blocks scratches. EVA combines paper aesthetics and sponge elasticity.
Note: Use short fluff only; long fluff may catch jewelry clasps.
-
Cosmetics / Electronics (shock-sensitive, mass production, transparent display)
Preferred: Plastic blister tray
Reason: Requires ultra-high fixation precision. Blister liners have firm snaps to grip products tightly and prevent shifting during transport.
-
Food (compression-sensitive, eco-focused)
Preferred: Paper card folding tray
Reason: Safe and hygienic for food contact; high rigidity prevents crushing by heavy items above.
