1. The 4 Layers of Export Glassware Protection

Ocean freight exposes glassware shipments to high-amplitude harmonic engine vibrations, severe container shifting during heavy seas (sway/roll), and forklift handling shocks. To eliminate transit breakage, Jingyue Glass implements a strict 4-tier packaging architecture:

Tier 1: Glass Contact Liner

Silk tissue paper wrapping or anti-scratch PE polybags prevent surface friction, electrostatic dust adhesion, and label abrasion during transit.

Tier 2: Cushioning Insert

High-density CNC molded EVA foam (38°–45° Shore C) or pre-formed EPE Pearl Cotton clamshells encapsulate each item individually with zero internal movement.

Tier 3: Rigid Gift / Inner Box

1200g–1800g greyboard magnetic book boxes or solid pine wooden boxes dissipate crushing loads and provide luxury retail unboxing appeal.

Tier 4: 5-Ply Export Master Carton

Reinforced double-wall corrugated cartons (275 lbs/sq.inch burst test strength) with 4-corner heavy-duty paper edge protectors.

3. Palletization & Container Loading Protocols

Proper container loading is just as critical as individual box packaging. For full container load (FCL) and less-than-container load (LCL) shipments:

4. Frequently Asked Questions

Can we customize the master carton with our brand logo and shipping marks?
Yes. We provide full customization of export carton printing including your corporate logo, item SKU, gross/net weight, FNSKU barcodes, and fragile warning symbols in black or full color.
How many cartons can fit in a 20GP or 40HQ container?
A standard 20GP container holds approximately 28 CBM (~700–850 cartons depending on SKU dimensions), while a 40HQ holds 68 CBM (~1,800–2,200 cartons). You can simulate your exact SKU combination using our Container CBM Calculator.
