Packaging teams today are under pressure to do more with less—control costs, maintain uptime, reduce material use, and support sustainability goals, all without disrupting production. Customers choose Sealstrip for simple integration, system reliability, material efficiency, and sustainability alignment, delivered in a way that fits into existing packaging operations without adding capital burden or operational risk.
Sustainability in packaging is no longer a mere trend; it is becoming a necessity driven by environmental concerns and regulatory demands. Among the most promising advancements in this realm are monomaterials, single-material compositions that offer a host of benefits over traditional multilayered packaging. For packaging engineers, understanding the potential of monomaterials is crucial for developing future-ready solutions.
Dive into the top 3 strategies CPGs are implementing to achieve sustainability goals - and how Sealstrip can help your packaging go green!
Food waste is an enormous, expensive problem — and most of it happens after the groceries are home. ReFED estimates that about a quarter of the U.S. food supply goes to waste each year, and consumer households are the single biggest source. USDA puts total U.S. food waste at roughly 30–40% of the food supply, and the UN’s 2024 Food Waste Index attributes about 60% of global food waste to households. A large share of that is simply food that goes stale or spoils after the package is opened — which is exactly where resealable packaging earns its keep.
Medical and pharmaceutical packaging carries two demands at once. It has to open cleanly and reliably in a clinical setting — often with gloved hands, under time pressure — and it has to show at a glance that the package hasn’t been opened or tampered with before it reaches the patient. Those aren’t competing goals: the right easy-open feature is also your tamper evidence. Here’s how to think about it, and which Sealstrip features fit.
Tamper evidence is about trust: a shopper, a clinician, or a regulator needs to see instantly that a package hasn’t been opened since it left the plant. In flexible packaging, that proof comes from a feature that can’t be undone once it’s been used. Here’s how tamper evidence works in flexible packaging, and which Sealstrip features deliver it.
Shrink film and overwrap protect a product beautifully — and can be miserable to open. Anyone who’s gone after a shrink-wrapped package with keys or scissors knows the feeling the industry calls “wrap rage.” The fix is a built-in easy-open feature applied as the package is wrapped. Fittingly, easy-open shrink packaging is where Sealstrip started — the company’s very first product, back in the late 1960s, solved exactly this — so here’s how today’s options work and how to choose.
Extended Producer Responsibility (EPR) has changed the math on packaging. In a growing list of U.S. states — including California, Colorado, Oregon, Minnesota, and Maine — and across the EU, producers are now financially responsible for the end-of-life of the packaging they put on the market. That turns every design choice, right down to a reseal or easy-open feature, into a line item on your compliance bill. The good news: the moves that lower your EPR fees are ones Sealstrip is built to support — so you can treat this guide as your EPR playbook rather than standing up a separate program.
When packagers look at a new convenience feature, the real question usually isn’t “does it work.” It’s “what will it do to my line?” New packaging equipment is expensive and disruptive. That’s the whole idea behind a retrofit applicator — and it’s how every Sealstrip system is built.
“Resealable packaging” isn’t one thing. It’s a family of mechanisms, each with its own strengths and best-fit products. Sealstrip has spent decades building reseal systems for flexible packaging, so here’s a plain-language tour of the main options — enough to talk comfortably with your packaging engineer and pick the right fit.
