High-Precision Packaging Solutions: Engineering Reality into ROI

From achieving 0.1mm technical precision to reducing EPR taxes by 80% — discover how our R&D and integrated manufacturing solve complex packaging challenges for global brands.

Leoprint critical safety label on stain-resistant furniture surface, demonstrating high-tack adhesion.

Challenge

Modern furniture lacquers Low Surface Energy (LSE) repel standard glue. The client needed a permanent, tamper-proof safety label on a surface specifically engineered to reject adhesion.

Solution

We implemented an ultra-aggressive adhesive that "bites" into LSE surfaces. Our engineering victory was mastering the processing of this sticky material to ensure it runs flawlessly on automatic lines.

Leoprint high-precision medical assembly labels with ±0.1mm die-cutting tolerance.

Challenge

Intersurgical required functional labels with an exact ±0.1mm tolerance. Standard converting equipment, which typically drifts up to ±1.0mm, was simply not accurate enough for their automated assembly lines.

Solution

We engineered a proprietary "Zero-Drift" slitting process that eliminates lateral movement entirely. This allowed us to consistently hit the ±0.1mm target, ensuring flawless application on the client’s precision robotics.

Leoprint patented easy-open banderole on an industrial roll for DEISS.

Challenge

DEISS envisioned a premium "Easy-Open" banderole, but standard technology failed to deliver. The dilemma was achieving a clean, instant "snap" opening without the adhesive resisting or damaging the roll during removal.

Solution

We engineered a patented mechanism that combines non-linear perforation geometry with precise adhesive deactivation. This ensures the banderole releases instantly and detaches completely, delivering a flawless function without product damage.

Leoprint recyclable tea envelope for high-speed packing lines (PAP 22).

Challenge

High taxes (~990 €/t) on composite laminates threatened margins. The goal was to eliminate plastic to cut costs without slowing down high-speed packing lines.

Solution

We engineered a 70gsm Barrier Paper (PAP 22). It runs at full production speed but reduces plastic content to <5%, unlocking the lowest tax tariff.

Leoprint recyclable premium PAP 22 barrier paper for Birchall tea envelopes with vibrant high-definition print.

Challenge

Winner of 15 consecutive "Great Taste Awards," Imporient refused to let eco-friendly materials downgrade their image or efficiency. They needed a sustainable solution that looked premium and didn't slow down their high-speed lines.

Solution

Replaced plastic with a recyclable barrier paper engineered to run flawlessly on fast packing machines without compromising the premium tactile feel.

Leoprint Recyclable dry food flow wrap packaging matching legacy material mechanics for zero speed loss.

Challenge

Skanėja needed to replace high-tax plastic laminates with recyclable paper. The critical requirement: the new material had to run flawlessly on existing lines without disrupting 20 years of established operations.

Solution

A recyclable paper alternative (PAP 22) that matched the mechanics of legacy plastic films, requiring zero speed loss or expensive machine modifications.

Leoprint ultra-removable labels on thin bioplastic bags for Plasta.

Challenge

Plasta's shift to ultra-thin (7-micron) bags created a "stickiness paradox." Labels needed strong tack to survive high-speed production, but standard adhesives were too aggressive, tearing the delicate plastic when the consumer tried to peel them off.

Solution

We engineered a "High-Tack / Low-Peel" adhesive system. It provides the instant grip needed for manufacturing stability but releases gently in the consumer's hands, ensuring the label peels away without damaging the bag.

Leoprint home-compostable envelope for biodegradable tea bags.

Challenge

Premium organic brands sought to align their outer packaging with their biodegradable tea pyramids. The goal was a nature-based solution that completes their sustainable vision with a genuine, high-end tactile experience.

Solution

We engineered a Paper / NatureFlex™ Hybrid. This structure provides the tactile luxury of paper with a certified home-compostable bio-barrier for aroma protection.

Leoprint custom kraft and BOPP laminates for Art Glacio private label.

Challenge

The client faced a commercial dilemma: their Private Label customers demanded premium "Craft" laminates, but traditional multi-step manufacturing made these materials too expensive for mass-market contracts.

Solution

Our single-pass "Inline" technology broke the cost barrier. By printing and laminating in one step, we enabled the client to offer premium barrier packaging at a competitive price point.

Leoprint high-performance barrier paper bags for aroma protection with premium tactile shelf appeal.

Challenge

"Skonis ir Kvapas" sought to align their premium brand with sustainability. However, standard eco-papers compromised both the luxury aesthetic and the essential barrier needed to preserve the delicate aroma of their fine teas.

Solution

Proving that mono-materials can look premium. We engineered a protective barrier coating that maintains shelf-life while allowing for intricate, vibrant flexo printing.

Leoprint smart double-sided banderole for BioBag compostable rolls.

Challenge

BioBag needed to double their message space without increasing label size. However, utilizing the reverse side was technically risky: standard adhesive would permanently bond to the sticky compostable plastic, destroying the product.

Solution

We engineered a double-sided banderole with "deadened" adhesive zones. This unlocked the reverse side for instructions, ensuring the label carries more info but peels off cleanly without damaging the delicate bag.

Leoprint sustainable heat-sealable paper for high-speed sugar sticks.

Challenge

Existing high-speed machines use ultra-narrow sealing jaws to save material. Standard heat-seal paper fails to bond on such small surface areas, causing packages to burst.

Solution

We developed a High-Tack Dispersion Coating. It activates instantly and creates a fiber-tearing bond even on minimal sealing zones, requiring no modifications to the machine.
