LDPE / HDPE Collation Shrink Film Printing Ink — Chemi Series | Bangladesh

Machine Specification

Where collation shrink ink is used

Collation shrink is the standard multipack format across Bangladesh’s beverage and consumer-goods retail — the 6-pack of water bottles, the 12-pack of juice cartons, the bundled promotional multipacks. The film starts as printed flat LDPE or HDPE, is wrapped around the multipack, then heated in a shrink tunnel to conform tightly to the bundle. During the shrink process the printed graphic stretches and distorts unless the ink is specifically formulated to move with it.

Chemi Shrink Coll is formulated for that heat-shrink behaviour. The ink pigments flex without cracking, adhesion holds through the shrink cycle, and the printed graphic remains clean and legible on the final bundle. Standard flexo and roto printing lines used for shrink-film in Bangladesh run this ink without equipment modification.

Applications

The largest applications are beverage multipack shrink (water 6-packs, soft drinks, juice cartons — a very high-volume category), consumer-goods multipacks (biscuit multipacks, snack bundles, personal-care multi-buy promotions), and promotional shrink wraps (festival and seasonal multipack promotions where the shrink wrap carries campaign graphics). The category grew significantly during the Ramadan and Eid retail seasons in recent years.

For film converters expanding into printed collation shrink for retail multipack contracts, Chemi Shrink Coll is a proven, brand-buyer-accepted ink that removes a common source of graphic rejects during the shrink cycle — a frequent quality issue with generic shrink-film inks.

Frequently Asked Questions

Will this ink work on both LDPE and HDPE film?

Yes — Chemi Shrink Coll is formulated for both. LDPE gives more shrink and is used for tight-fitting bundles; HDPE is stiffer and used for larger bundle formats. Ink chemistry accommodates both.

Does the printed graphic distort during shrink?

The ink flexes with the film — graphic dimensions change proportionally during shrink but the ink itself does not crack or lift. Graphics must be designed with the shrink ratio in mind (typically 20–40% shrink depending on film grade).

What printing method works best?

Flexographic is standard for volume shrink-film printing in Bangladesh; roto-gravure is used for higher-end brand work with photographic graphics. Both are supported.

Is the ink food-contact safe for the multipack contents?

The ink is on the outside of the shrink wrap — no direct food contact with the packaged product. Standard food-adjacent migration compliance applies; documents available on request.

What container sizes are stocked?

Standard 25kg drums; bulk drums on order for high-volume converters. Local Dhaka stock for common colours.

What is the delivery time in Bangladesh?

Standard colours ship within 3–7 days from Dhaka. Custom brand-specification colours from Chemicoat take 30–45 days.
