How much time do fast assembly boxes save?

Typically 20–50% per pack compared with RSC plus base taping, depending on workflow and contents.

Are they strong enough for heavier loads?

The overlapping crash-bottom provides excellent stability. For dense items, step up board grade or switch to double wall cartons.

When should I use a Book Wrap instead?

For single books/media and flatter items where variable depth and edge protection are key—use ColomPac Book Wraps at https://packexact.com/book-wraps/.

ColomPac Fast Assembly Boxes

Q: Do ColomPac boxes include tear-open strips?

Many variants include an integrated tear strip for clean opening and smoother returns.

Accelerate your eCommerce packing with ColomPac fast assembly boxes (instant-bottom / auto-lock base). Pop open to a locked crash-base, close with a self-seal lid, and deliver a cleaner, more consistent unboxing at scale.

What makes them fast?

Instant pop-up base: the crash-lock bottom auto-engages—no base taping, no fumbling.

Self-seal closure: peel, press, done. Many variants add an integrated tear strip for customer-friendly opening.

Flat-packed, space-efficient: store more on the shelf; assemble in seconds when orders drop.

Where ColomPac shines

High-throughput benches, subscription kits and premium D2C where speed and presentation matter. For single books/media, switch to ColomPac Book Wraps to gain edge protection and flexible depth.

Need inserts? Add cardboard sheets as base/top pads.

Benefits & features

Speed at the bench

Shave seconds per order with a pop-up base and peel-&-seal lid—less tape, fewer steps, more output.

Secure, stable base

Overlapping crash-base resists splay and improves stacking during handling and transit.

Premium unboxing

Clean lines, tidy seals and tear-open convenience elevate the customer experience and reduce returns friction.

Best-fit use cases

Subscriptions & gifting: beauty, wellness and lifestyle kits with minimal tape for a neater reveal.

Electronics & accessories: stable base + easy-open lid; add bubble wrap or paper void fill.

Jarred goods / homewares: layer with cardboard sheets to separate and spread load.

Mixed multi-item orders: build in tiers using base/top pads, then seal with packing tape if additional security is needed.

3PL & multi-shift teams: fewer steps means consistent results across operators and shifts.

Switch to Book Wraps: for single titles and flatter mail, see ColomPac Book Wraps.

How to pack ColomPac fast assembly

1) Pop & lock: open the box so the base auto-locks; press corners to seat fully.

2) Base support: add a cardboard sheet for heavier/fragile loads.

3) Stabilise: use paper void fill or bubble wrap to remove movement.

4) Seal: press the self-seal top; reinforce with tape if required by your carrier.

5) Docs & labels: apply labels and attach paperwork with Documents Enclosed wallets.

Size & selection tips

Work to internal L × W × H (mm) after wraps/inserts. Leave 10–15 mm clearance for cushioning and to avoid crush. For very dense contents, step up board grade or switch to double wall boxes.

For flatter shipments (books/media), a ColomPac Book Wrap may reduce DIM weight and improve edge protection.
