HLunPACK Successfully Delivers High-Speed Milk Powder Packaging Solution with Data-Driven Static Control Upgrade

HLunPACK recently completed the delivery of a fully automated milk powder packaging system together with customized packaging materials for a dairy customer. Through coordinated optimization of machinery and film structure, HLunPACK successfully resolved severe static adhesion issues during high-speed production, enabling stable and efficient continuous operation.

As a fine and highly flowable powder product, milk powder requires high standards in hygiene, sealing integrity, production stability, and packaging efficiency. During high-speed filling, constant friction between powder particles and packaging film can generate significant static electricity, resulting in film blocking, bag adhesion, unstable film tracking, and sealing interference. These challenges become more critical as production speed increases.

To meet the customer’s product requirements and output targets, HLunPACK initially supplied a high-barrier laminated structure of PET / VMPET / PE, designed to ensure moisture protection, oxygen barrier performance, and reliable sealing properties.

Material functions included:

* PET Layer – excellent printability and mechanical strength

* VMPET Layer – oxygen transmission rate below 1.0 cc/㎡·24h for superior barrier protection

* PE Layer – heat seal strength of ≥35 N / 15mm, suitable for high-speed packaging lines

During the initial production phase, the packaging line operated steadily at 60 bags per minute, while maintaining a finished product qualification rate above 99%.

As the customer later increased capacity requirements, production speed was raised to over 85 bags per minute. Under this condition, static charge accumulation intensified rapidly, causing film attraction and bag sticking. Manual intervention increased to 6–8 times per shift, negatively affecting production efficiency and line continuity.

In response, HLunPACK engineering specialists launched an immediate optimization program. By incorporating food-grade anti-static masterbatch and food-grade slip/opening additives into the inner sealant layer, the film’s charge dissipation performance and layer separation efficiency were significantly improved.

After implementation and on-site validation, the upgraded solution delivered measurable results:

* Surface static level reduced by approximately 65%

* Stable packaging speed increased to 100 bags per minute

* Manual interventions reduced from 6–8 times to less than once per shift

* Continuous stable runtime extended from 2 hours to over 8 hours

* Finished bag adhesion rate reduced by approximately 90%

* Overall production capacity increased by 28%–35%

The customer confirmed that the upgraded packaging system fully met its high-speed mass production targets while reducing downtime losses and labor management costs.

This project once again demonstrates HLunPACK’s comprehensive strengths in packaging machinery, functional packaging material development, and high-speed powder packaging integration. We do not simply supply machines—we deliver measurable, scalable, and production-ready packaging solutions.

HLunPACK will continue serving global customers in dairy, nutrition powder, food, and pharmaceutical industries with more efficient, reliable, and competitive intelligent packaging systems.
