Tooling customizationFlexible and rigid packaging tooling customization services meet and overcome process and machinery geometry challenges. Customized tooling improves durability and generates the best designs for faster changeovers and easier maintenance.

United Silicone combines proprietary materials and processes with in-house design, manufacturing and machining to provide complete custom packaging tooling solutions. USI proprietary processes include Teflon™ (PTFE) bonded silicone.

• Operational packaging automation flexibility
• Ideal tooling geometry that meets packaging process requirements
• Tooling designs that optimize dwell times, pressures and temperatures for strong and leak-free seals

United Silicone makes, modifies and restores precision rollers, with or without silicone-to-metal bonded surfaces, for precise packaging film handling applications.

Silicone-to-metal bonded rollers can be designed for constant-heat sealing applications also.

Typical inline flexible packaging applications
Flexible packaging automated inline applications that benefit from silicone-to-metal bonded customized tooling include:

• Pouch manufacturing machinery
• Bag and pouch form-fill-seal packaging
• Spouted or fitment pouch manufacturing
• Pre-made bag, pouch and spouted pouch filling and sealing machinery

Mono-material* film and rigid packagingPlastic packaging film, bag, pouch and spouted pouch manufacturers are behind much of the ongoing innovation in packaging materials.

These manufacturers are rapidly developing mono-material bags, pouches and spouted pouches. This push for new material innovations includes new mono-material film and rigid packaging combinations.

ISM and United Silicone will work with you to optimize your flexible and rigid packaging heat seal tooling to handle mono-material films and sealing.

*Mono-material flexible packaging uses plastic films with one or more layers of the same polymer for easy recycling. By matching the material types of lidding film and rigid packaging, the combination becomes mono-material packaging, which is recycle-ready also.

Typical inline rigid packaging applicationsRigid packaging automated inline applications that benefit from silicone-to-metal bonded customized tooling include:

• Sealed tray lidding sealing
• Blister and clamshell packaging
• Cup, pot and tub lidding sealing
• Film handling for lidding sealing sub-systems
• Lidding sealing for thermoformed form-fill-seal rigid and semi-rigid packaging systems

Form-fill-seal (FFS) flexible packaging solutions for bagging and pouchesVertical-form-fill-seal (VFFS) and horizontal-form-fill-seal (HFFS)* customized tooling solutions for:

• Film handling
• Bag and pouch forming
• Filled bag and pouch sealing

*Horizontal form-fill-seal packaging includes flow packaging, flow packs and wrap packaging.

Packaging film handling
Form-fill-seal bag and pouch packaging use continuous flat rolls of plastic film. Precision-made metal and silicone-to-metal bonded roller design, fabrication and renewing services are available for film handling applications.

Who uses United Silicone precision tooling?
United Silicone provides heat sealing and film handling tooling solutions for automated packaging applications. Engineering and technical professionals who use United Silicone to help solve their packaging problems include:

• Design Engineers
• Production Planners
• Procurement Managers
• Packaging Machinery Integrators
• Maintenance, Repair and Operations (MRO)
• Integrated Primary Food Packaging Machinery Designers and Manufacturers

Flexible and rigid food packaging challengesNew, developing and ongoing industry trends and challenges for packaging make heat seal tooling customization and optimization more necessary than ever.

Food safety and hygiene challenges
Food safety and hygiene trends drive increased packaging automation that minimizes or eliminates "hand touch" during processing. Increased automation means faster production rates, which require more precise heat seal optimization and tooling.

Challenging growth of e-commerce
Increased e-commerce purchasing by consumers puts greater demands on packaging and seal integrity. Packaging should be able to withstand the rougher handling associated with order processing and shipping.

Personalization and product differentiation challenges
Greater personalization (personalized products) and product differentiation mean more frequent product line changeovers. It also means tooling needs to be more accessible, faster and easier to change and maintain.

Challenges from the increasing use of recycle-ready, mono-material packaging
Mono-material lidding and bag/pouch films continue to be developed and deployed throughout the flexible and rigid packaging markets. Sealing mono-material films require more precise heat sealing optimization.

Responsible plastics use
Responsible plastic packaging use means minimizing plastic use. Minimizing plastic use means redesigning plastic packaging to reduce its weight without compromising performance. Lighter weight packaging reduces material use and shipping costs and is encouraged by tax incentives in some markets to promote recycling-ready packaging.
