eCommerce Crash Lock Boxes

Speed up fulfilment with crash lock boxes (auto-lock base cartons). The base snaps into place in seconds—no taping required—so you can pick, pack and ship faster with a neater, safer seal and a better unboxing experience.

What is a crash lock box?

A crash lock (auto-lock) box features a pre-glued base that automatically locks when you pop it open. Unlike standard RSC cartons that need bottom taping, a crash lock forms a strong base instantly—ideal for fast eCommerce packing benches.

Why eCommerce teams choose them

Faster packing: cut seconds per order across shifts. Stronger base: reliable hold for heavier or fragile goods. Cleaner look: fewer tapes and a premium feel for returns & gifting.

Benefits & features

Auto-lock speed

Base locks instantly—no bottom taping. Improve throughput and consistency on busy benches.

Secure base strength

Pre-glued crash-base design resists splaying under load—ideal for glass, cosmetics, electronics.

Returns-friendly options

Add peel-and-seal closures and tear-strips for easy, tamper-evident returns and better CX.

Best for these eCommerce workflows

Fast pick & pack: subscription boxes, cosmetics, health & beauty, D2C electronics.

Giftable orders: premium presentation without excess tape.

Returns flows: peel-and-seal + rip-strip enables quick customer returns.

Fragile or liquid goods: stable base for bottles and jars—pair with bubble wrap and void fill.

Kitting & inserts: supports cardboard sheets as trays/dividers for multi-item orders.

Multi-channel fulfilment: repeatable pack quality across teams and shifts.

How to pack crash lock boxes efficiently

1) Pop & lock: press the sides; the base auto-locks. Check corners are seated.

2) Line & protect: add a base cardboard sheet or pad for heavy/fragile goods.

3) Load & stabilise: place items; fill voids with paper void fill or bubble.

4) Seal top: close flaps and seal with tape or use peel-and-seal if specified.

5) Documents & labels: affix Documents Enclosed and labels.

Why this workflow works

Speed: removing bottom-taping saves cumulative time per order.

Integrity: the crash base resists burst forces better than untaped RSC bottoms.

Consistency: fewer manual steps mean fewer packing errors across teams.

Experience: tidy, tamper-evident finishes improve unboxing and returns.

Choosing the right crash lock size

Measure internal L × W × H (mm). Allow room for protective wraps and inserts. For very heavy or stacked consignments, consider double wall.

RSC Single Wall

Budget everyday cartons. Requires bottom taping; slower but very cost-effective across sizes.
