Oil Slick® Clear FEP Sheets

Oil Slick Clear FEP Sheets are precision-cut nonstick squares designed for extraction labs, processors, and serious concentrate handlers who need a reliable barrier between sticky product and everything else. Each 4 in × 4 in (10.2 cm × 10.2 cm) sheet measures just 0.05 mm (0.002 in) thick—thin enough to fold cleanly without cracking, but tough enough to shrug off aggressive terpenes that would haze or warp standard plastics. Available in bulk packs of 500, 1,000, or 5,000 sheets, these are built for operations that burn through packaging materials and can't afford yield loss to sticky surfaces.

Key benefits

• Recover every last bit of product — FEP's true nonstick surface means oils, sauces, and terp-heavy blends peel away clean instead of smearing into the film and staying there.
• Terpene-resistant without clouding — high-terpene formulations can eat through cheaper plastics over weeks, but FEP holds up without warping, hazing, or breaking down.
• Crystal-clear visibility — fully transparent film lets you inspect color, texture, crystallization, and inclusions without unwrapping or fighting glare.
• Folds without fighting back — at 0.05 mm (0.002 in), these crisp-fold like paper but won't permanently crease, crack, or shatter the way rigid plastics do.
• Consistent sheet to sheet — whether you're running R&D samples or full production batches, the film behaves the same every time, so your SOPs stay locked in.
• Bulk packs for real throughput — 500, 1,000, or 5,000-sheet options mean you're not constantly cracking new packages or babysitting inventory mid-run.

Best for

Licensed extraction labs and processors running solventless or hydrocarbon systems who need a neutral, chemically resistant contact surface between concentrate and packaging. Serious home extractors pressing rosin who want to stop losing yield to paper and cheap parchment. QA teams who need to visually inspect batches without rehandling product. Anyone who's graduated past "good enough" packaging and wants materials that actually match the quality of what they're making.

How to use them

Think of these as precision nonstick tiles for the space between "fresh off the collection tool" and "sealed and ready to ship." Lay a sheet flat on your bench, scale pan, or tray, then stage or portion concentrate directly onto the FEP. From there, fold, tent, or wrap as your workflow needs—the film will peel away clean when it's time to move product.

For short-term staging, stack filled sheets in a tray or on a silicone dab mat to keep things organized and off raw stainless. The thin profile means you can fold edges over gently without trapping air pockets or creating sharp creases that damage the material.

A lot of labs use these as inner liners: drop a sheet into a jar, clamshell, or branded box, place product on top, and let the FEP be the only thing touching your concentrate. If anything sticks, you're peeling film away instead of scraping expensive packaging. Works especially well inside heavy-bottom glass jars when you want that extra barrier between concentrate and lid.

Why FEP over other materials

FEP (fluorinated ethylene propylene) sits in the same fluoropolymer family as PTFE but brings specific advantages at thin gauges. It offers glass-like smoothness and strong chemical resistance while staying flexible—exactly what you need when handling sticky oils and aggressive terpene profiles. In practice, that translates to fewer micro-tears, less clouding over time, and a more predictable surface every time you grab a sheet.

The transparency is the other big differentiator. Standard parchment and PTFE are opaque or translucent at best, which means you're constantly unwrapping to check product. With clear FEP, you can visually QC color gradients, crystallization patterns, and particulate contamination without rehandling anything. Handy when you're showing off batches to clients or running quality checks across a production run.

Compared to silicone sheets, FEP won't absorb odors or flavors over time. Compared to standard plastic wraps, it won't break down when terpenes get aggressive. It's not the cheapest option, but it's the one that doesn't make you choose between convenience and product integrity.

Specifications

Workflow integration

The 4 in × 4 in (10.2 cm × 10.2 cm) precut size drops straight into most small-format packaging flows without trimming. If you need different dimensions, they cut cleanly with scissors, a paper cutter, or a sharp blade—easy to dial in for custom branded boxes, display tins, or specific scale pans.

For larger facilities, bulk packs of 1,000 or 5,000 sheets keep operators from constantly opening new packages, and inventory becomes dead simple: a stack of squares instead of half-used rolls with torn edges. Smaller labs can run comfortably on 500 sheets for R&D, stability samples, and a steady order flow without worrying about running dry mid-project.

These pair well with other packaging materials too. Use them as inner liners for mylar bags when you want extra protection during shipping, or slip them inside branded containers so customers peel FEP away instead of scraping the inside of your packaging.

Care and reuse

These sheets can go multiple rounds depending on what they've touched and how you handle them. After use, let any residue cool, then gently peel or wipe it off. For deeper cleans, rinse with isopropyl alcohol or appropriate lab-safe solvents, then let them dry completely before putting them back into rotation. Inspect for scratches, tears, or clouding before reusing on client-facing or regulated product.

Store unused sheets flat in a clean drawer, folder, or sealed bag to keep them dust-free and crease-free. If you're staging multiple strains or batches, labeling outer packaging or pairing sheets with clearly marked storage containers keeps everything organized and prevents mix-ups.

FAQ

• Can I reuse these, or are they single-use?
  They're reusable if you keep them clean and handle them carefully. Many labs reuse sheets several times for in-house staging, R&D, or similar products. For client-facing or highly regulated applications, follow your internal SOPs and inspect each sheet for damage, contamination, or cloudiness before putting it back in rotation.
• Can I cut these to different sizes?
  Absolutely. They cut cleanly with scissors, a paper cutter, or a sharp blade. That makes it easy to size them for specific jars, clamshells, or custom packaging dimensions. If you're fitting them inside other containers, cutting slightly smaller than the inner dimensions usually works best.
• What's the difference between FEP and PTFE sheets?
  Both are fluoropolymers with strong nonstick properties and chemical resistance. The main differences: FEP in this thin gauge gives you full transparency and more flexibility, so you can see product clearly and fold without cracking. Thicker PTFE sheets work better for lining trays or presses where you need more rigidity and don't care about visibility.
• Will terpenes or solvents damage these over time?
  FEP handles most terpenes and common lab solvents without warping, hazing, or breaking down—it's the same reason FEP is used in a lot of labware and chemical tubing. Under normal handling temperatures and conditions, you shouldn't see the degradation that happens with standard plastics. Keep them away from open flames and extreme heat, and they'll hold up.
• Are these food-grade certified?
  FEP is widely used in laboratory and industrial applications, but these specific sheets aren't being sold with formal food-grade certification. If your market or facility requires specific regulatory ratings for direct-contact materials, confirm with your compliance team before using them that way.
• How do I store unused sheets?
  Keep them flat and sealed—document folders, clean drawers, or the original packaging inside a cabinet all work. The goal is dust-free and crease-free. If you're running multiple SKUs, labeling where everything is keeps your packaging station organized.
• Do these work with other Oil Slick products?
  They integrate well as liners or contact barriers alongside concentrate jars, silicone mats, and other gear in the lineup. As long as you keep them away from direct flame, they'll slide into most concentrate handling workflows without any compatibility issues.
