Inline Packaging

What Inline Packaging does

Inline Packaging LLC is a privately held B2B manufacturer of microwave susceptor packaging, headquartered in Princeton, Minnesota (11-50 employees). The company designs, develops, and produces active packaging that converts microwave energy into high surface temperatures to crisp and brown foods in microwave ovens, serving food manufacturers across applications including pizza, egg rolls, wraps, taquitos, popcorn, sandwiches, and corn dogs. Its product portfolio spans multiple physical formats — sleeves, heat seal wraps, heat seal cartons, crisping trays, die-cut pads, popcorn rollstock, and susceptor patches — supported by two proprietary in-house technologies: Superceptor™ (variable heat output for difficult-to-crisp foods) and Micro-Grill™ (focused energy patterns that simulate a Panini grill in a microwave).

The company's core differentiator is a proprietary single-pass manufacturing process that combines susceptor patterning, printing, laminating, and die-cutting into one operation, which the company states is the only such capability in the world. Its technical team has collectively been awarded 27 patents on microwave packaging and processing innovations developed over a 30-year horizon. The revenue model is project-based B2B sales of custom-engineered packaging to food manufacturers, with quote-based pricing per specification and volume, distributed through direct sales rather than resellers. Customer engagement is high-touch, with Inline Packaging's product development team involved from conception to completion of each package.

The company has limited public visibility, with the most recent documented activity being product launches and award wins in 2006 (AIMCAL Technical Award for POPZ Microwave Popcorn) and 2007 (Anuga Innovative Product Award for the ConeInn Pizza Cone susceptor sleeve). The company has no disclosed funding rounds, no institutional investors, no M&A activity, and no public leadership bios. Its customer base is concentrated in food manufacturers, with only two named enterprise customers referenced in the available material (Soller LLC and ConeInn), and its geographic reach is described as North America via direct manufacturing supply.

Core offering

Inline Packaging designs, develops and manufactures active microwave susceptor packaging that converts microwave energy into high surface temperatures to crisp and brown foods. Its core offering is delivered in multiple formats — trays, tubs, cartons, wraps, bags, sleeves, die-cut pads and rollstock — engineered for individual food products and supported by exclusive Superceptor™ and Micro-Grill™ technologies for difficult-to-crisp items.

Product overview

Inline Packaging is a leader in microwave susceptor food packaging, offering a unified portfolio centered on active susceptor technology. The core offering is Microwave Susceptor Packaging, enhanced by two proprietary technologies: Superceptor™ (for supercharging heat output on difficult-to-crisp foods) and Micro-Grill™ (for turning microwaves into Panini grills). These technologies are applied across multiple product formats including Sleeves, Heat Seal Wraps, Heat Seal Cartons, Microwave Crisping Trays, Die Cut Pads, Popcorn Rollstock, and Susceptor Patches. The company operates the only plant in the world with the capacity to susceptor pattern, print, laminate and die-cut in a single pass operation.

Brands

• Superceptor™: Revolutionary microwave susceptor packaging technology that supercharges heat output for foods difficult to crisp such as pizzas, eggrolls, and sandwiches. Features variable heat output with increased heat in select areas like the center of a pizza.
• Micro-Grill™

Products and services

• Microwave Susceptor Packaging Active packaging that absorbs microwave energy and converts it to high surface temperatures, crisping and browning foods in microwave ovens. Available in many forms including trays, tubs, cartons, wraps, bags and sleeves; engineered to specific food product requirements. Sold to food manufacturers.
• Superceptor™ Susceptor Technology Revolutionary supercharged susceptor technology that increases heat output for foods difficult to crisp such as pizzas, eggrolls and sandwiches. Features variable heat output that adds heat in select areas (e.g., center of pizza) for even cooking without overcooking edges. Sold to food manufacturers as a differentiated susceptor solution.
• Micro-Grill™ Susceptor Technology Susceptor technology that turns a microwave oven into a Panini grill, with focused energy pattern for enhanced grill lines, vertical and horizontal moisture vent channels, increased susceptor heat output, and multiple paperboard layers for rigidity and moisture resistance. Sold to food manufacturers.
• Microwave Susceptor Sleeves Paper or board laminated to metallized microwave susceptor film, customized with vents, opening zippers, and gussets for proper fit. Designed for hand-held foods such as egg rolls, wraps, enchiladas and corn dogs. Sold to food manufacturers.
• Heat Seal Wrap Paper laminated to metallized microwave film with a sealable surface for use on flow wrappers. Custom designed to seal via registered heat seal coating and suitable for high volume production of foods such as sandwiches, calzones and pies. Sold to food manufacturers.
• Heat Seal Cartons Cartons designed for high-temperature applications such as microwave popcorn and other food products where heat seals must not be in contact with the product. Sold to food manufacturers.
• Microwave Crisping Trays Trays for items such as french bread pizza and other products, available in custom designs and configured for hand-locked, machine lock-formed, press-formed or glue set-up construction. Sold to food manufacturers.
• Die Cut Pads Custom die-cut flat shapes matched to product size, used where the bottom of a product needs to be browned or crisped while the top does not benefit from additional heat. Most common application is a circular pizza disk. Sold to food manufacturers.
