Sealstrip

What Sealstrip does

Sealstrip Corporation is a privately held, WBENC-certified women's business enterprise that designs and manufactures pressure-sensitive tape systems and custom retrofit applicators for easy-open, resealable, and tamper-evident features on flexible packaging. Founded in 1979 (with predecessor entities tracing to 1959 via Formatron and 1967 via Tearstrip Systems, merged in 2002), the company is headquartered at a 103 Industrial Drive, Gilbertsville, PA facility that is AIB Superior Rated and IFS PACsecure (GFSI-recognized) certified, manufacturing FDA-compliant tapes and applicators sold worldwide. Its product portfolio spans Easy Open features (Peelwrap, Shrinktape, Teartape, VerdeSeal) and Resealable features (Peel&Seal, FreshPak and FreshPak BarrierPlus, FreshPak Integrated Design, Sealstrip namesake product, SealAcross, SealAcross for Trayed Products, Stand Up Pouch Reseal, Roll&Seal), supported by patented TamperTear tamper-evidence technology and ongoing patent activity.

The company sells direct to flexible packaging converters and CPG brands through a B2B field sales model, with revenue generated primarily from hardware sales of tape rolls and applicator systems, supplemented by custom sample development and in-plant trial services. Pricing is quote-based and not publicly disclosed. Its technology is differentiated by retrofit integration — applicators mount onto customers' existing VFFS baggers, horizontal flow-wrappers, and pouch machines without new equipment capex — and by sustainability positioning via VerdeSeal mono-material technology validated by TÜV Rheinland for a 66% carbon footprint reduction versus conventional adhesive technologies. Sealstrip serves a vertically-segmented base spanning Baked Goods, Candy & Snacks, Refrigerated & Frozen Food, Shelf Stable Foods, Fresh Produce, OTC/Personal Care, Medical Device/Pharmaceutical, Tortilla & Flatbread, Petfood Packaging, and Cheese Packaging, with named enterprise customers including Hershey's (Twizzlers), Pepperidge Farm (Goldfish Bread), Hunt's (Recipe Ready Tomato Paste), and Lundberg Family Farms.

The business operates with 11-50 employees and is led by President Heather Chandler (with the company since 1992), Director of Product Development Jo Anne Forman (former President and member of the founder's family), and Administrative Manager Rachel Conrad. Strategic OEM partnerships with PFM (vertical baggers and flow wrappers) and Ilapak (Vegatronic baggers) embed Sealstrip features into major converting equipment platforms, and the company maintains a multi-channel marketing presence including its own website, packaging insights blog, YouTube, LinkedIn, Facebook, and Instagram channels, supplemented by participation in Pack Expo, Sweets & Snacks Expo, Interpack, Snaxpo, Pack East, Canadian Bakery Showcase, and Private Label Show.

Broad incumbents

• AptarGroup: AptarGroup is a global leader in dispensing closures, sealing systems, and active material science for food, beverage, personal care, and pharmaceutical packaging. Comparable as a supplier of specialty closure/sealing technologies serving overlapping CPG end-markets.
• PAC Machinery: PAC Machinery is a long-established manufacturer of packaging and sealing machinery including heat sealers and bag closers. Overlaps with Sealstrip on the applicator/sealing equipment side, though PAC's portfolio is broader and not focused on pressure-sensitive tape features.
• Sonoco Products Company: Sonoco is a large diversified packaging manufacturer with a flexible packaging segment serving food, beverage, and consumer goods markets. Comparable at the customer-segment and converter level, though Sonoco's portfolio extends well beyond reseal/easy-open features.
• ProAmpac: ProAmpac is a leading global flexible packaging converter offering films, pouches, and reseal features (including Zip-Pak). Directly comparable on reseal technology via Zip-Pak, and overlaps significantly with Sealstrip's converter and CPG customer base.
• Sealed Air: Sealed Air (parent of Cryovac and Curwood) is a major flexible and protective packaging supplier with extensive reseal and easy-open capabilities. Comparable as a broad incumbent offering overlapping reseal/easy-open features to CPG converters, though at much greater scale.

Direct peers

• Zip-Pak (ProAmpac): Zip-Pak, now part of ProAmpac, is the dominant supplier of press-to-close zipper closures for flexible packaging — the incumbent format that Sealstrip's pressure-sensitive tape is designed to replace. Directly comparable in offering (resealable features) and customer base (CPG brands and converters).
• Scholle IPN: Scholle IPN is the leading bag-in-box packaging supplier with integrated fitment and closure technologies. Comparable to Sealstrip's Roll&Seal offering in the bag-in-box format and overlapping in food, beverage, and industrial liquid/semi-liquid end-markets.
• Pactech Packaging: Pactech designs and manufactures specialty reclosable and resealable packaging solutions including custom applicator systems for flexible packaging — closely mirroring Sealstrip's tape + applicator model and customer profile in specialty CPG.
• Hudson-Sharp Machine Company: Hudson-Sharp manufactures bag-making and converting machinery with integrated reclosable feature application (zipper, tape, and label applicators). Comparable as a machinery-and-feature supplier to the same flexible-packaging converter customers Sealstrip serves.

Emerging players

• Placon: Placon is a thermoformed and flexible packaging specialist with recyclable packaging innovations in food and consumer markets. Adjacent peer with comparable focus on sustainability-led reseal/easy-open features for CPG, though concentrated in thermoformed formats.
