Global environmental regulations are becoming stricter,
PETHard packaging (referring to various packaging applications not based on PET preforms) and multi-layer packaging technology have gradually become the mainstream in the industry. How to balance compliance, efficiency, and cost is a key issue in the food, daily chemical, and consumer goods industries.
In this issue of HUSKY Classroom, Kevin, the manager of Husky Packaging Systems and Solutions, will take you to quickly understand market trends and analyze how Husky's full process chain system control can achieve high-performance and sustainable packaging molding.
From regulatory driven material substitution to high difficulty thin-walled injection molding mass production
Moving on to the dual upgrade of functionality and environmental protection in innovative multi-layer packaging
01. Market Trend: Regulations are forcing upgrades, and PET has become the preferred choice
Global plastic packaging is accelerating its transition to PET. The EU Plastic Convention specifies that all packaging materials must be 100% recyclable by 2030, and plastic products must contain at least 55% recycled materials by 2035.
The overall recycling rate of the current industry is far from reaching the standard, and traditional PS, PE
PPDue to the difficulty of recycling and low recycling rate, the materials cannot meet compliance requirements.
In this context, PET has become one of the preferred alternatives to traditional packaging materials due to its excellent recycling properties. From cooked food boxes, ice cream boxes, disposable tableware, to fruit and vegetable boxes, candy and seasoning packaging, the application scenarios continue to expand, and the market growth space is vast.
But behind the opportunities, the industry also faces enormous technological challenges. The PET thin-walled injection molding process is difficult and requires extremely high injection pressure and speed. This pair of injection molding machines

02Husky Solution: Integrated System, Overcoming Multiple Challenges
Husky has been deeply involved in the packaging field for many years, and its core advantage lies in providing integrated melt conveying systems including injection molding machines, hot runners, temperature controllers, and remote diagnostic services for equipment. This ensures uniform melt quality from the source, achieving lower melt temperatures, more stable molding performance, and higher production efficiency. Husky provides customers with a "turnkey" solution for the entire life cycle from research and development to mass production.
01. PET hard packaging: high-quality production, covering all scenarios
Husky's integrated system solution has been successfully implemented and delivered in multiple application scenarios to address the industry pain points of PET thin-walled injection molding.
One step PET water cup injection molding:Achieve shorter molding cycles and higher efficiency.
Two step food can embryo/beverage cup embryo:A 1000 ton Hylectric 4.0 injection molding machine paired with a 32 cavity mold can achieve stable production with high cavity count, short cycle time, and high production capacity.
Disposable PET tableware:The 400 ton injection molding machine is equipped with 64 cavity molds with a cycle time of less than 10 seconds, meeting the requirements of large-scale low-cost production.
02. Multi layer packaging: strong functionality, material saving, and lower carbon emissions
Multi layer packaging is one of the innovative trends in the industry, with three core values: using barrier materials in the middle layer can extend the shelf life of sensitive foods, reduce production and logistics costs; Adopting color changing/gradient technology to enhance packaging aesthetics and brand recognition; Add recycled materials to the middle layer to balance functionality and low-carbon compliance.
At present, many high-end retail brands around the world are already laying out such applications.
Husky has mature experience in multi-layer injection molding and has delivered approximately 50 systems worldwide, covering scenarios such as coffee capsules and sensitive food cans.
Its advantages are significant:
Real case: 600 ton Hypersync injection molding machine+48 cavity mold used for producing multi-layer coffee capsule packaging, with a cycle time of 3.6 seconds (industry average 5.5 seconds); A 15 micron barrier layer extends shelf life by 10 times, significantly reducing costs.
The Canadian technology center is equipped with a 120 ton multi-layer application injection molding machine and a 4-chamber multi-layer hot runner to assist in small-scale trial production.
Husky's multi-layer injection molding technology can increase the proportion of recycled materials in the middle layer to over 50%, helping to promote a circular economy.
Whether it's efficient mass production of PET eco-friendly packaging or innovative upgrading of multi-layer packaging, Husky can provide a comprehensive one-stop system solution from high-performance injection molding machines, advanced hot runners, intelligent thermostats, to active value-added service models, helping you seize opportunities, comply with carbon reduction regulations, and achieve efficient profitability.
