| Unbleached Kraft Paper | Virgin or recycled kraft fibers; usually uncoated | 35–120 g/m² | Low to moderate without treatment | Low; absorbs liquid unless treated | Suitable for dry or short-duration warm-food contact; avoid direct oven use unless specified | Bread, bakery items, dry snacks, produce, takeaway bags, outer wraps | Good tear strength and natural appearance; select food-contact grade and recycled-fiber compliance for the destination market | Often recyclable when clean and uncoated; recycling acceptance varies by local system |
| Bleached Kraft Paper | Bleached kraft fibers; uncoated or lightly treated | 35–100 g/m² | Low to moderate without a functional coating | Low to moderate depending on treatment | Suitable for wrapping and interleaving; oven suitability requires product-specific testing | Bakery products, confectionery, sandwiches, dry foods, printed food wraps | Provides a clean white print surface; verify optical brightener, ink, adhesive, and food-contact requirements | Generally recyclable if uncoated, clean, and accepted by the local paper stream |
| Greaseproof Paper | Highly refined, dense paper with reduced porosity; may be treated | 30–90 g/m² | Moderate to high, depending on grade and test result | Low to moderate; not intended as a liquid barrier | Some grades are suitable for baking or hot-food contact; confirm temperature and time limits | Pastries, fried foods, sandwiches, cookies, confectionery, bakery liners | A strong option when grease control is needed without a plastic film; request oil and food-contact test data | Often recyclable if uncoated and not heavily contaminated; treatment can affect recyclability |
| Glassine Paper | Supercalendered, smooth, translucent paper with a dense surface | 30–90 g/m² | Moderate to high for light grease exposure | Moderate vapor resistance; limited protection against liquid water | Generally for room-temperature or moderate-temperature use; verify heat limits | Confectionery, bakery interleaving, tea sachet overwraps, dry and delicate foods | Smooth appearance and good printability; can improve product presentation but is less suitable for wet foods | Typically recyclable where accepted; avoid unnecessary laminations that complicate paper recovery |
| Silicone-Coated Parchment Paper | Parchmentized paper coated with food-contact silicone | 35–70 g/m² | High | Moderate; resists short-term moisture but is not a full liquid barrier | Designed for baking and cooking within the supplier’s stated temperature range; do not use under a broiler unless approved | Baking sheets, oven-ready foods, pastries, roasting applications, food separators | Non-stick performance reduces the need for added fats; request migration, temperature, and silicone-coating documentation | Usually not accepted in standard paper recycling because of the silicone coating; compostability depends on certification and local facilities |
| Wax-Coated Paper | Paper coated with paraffin, soy, or another specified wax | 40–100 g/m² | High for many greasy foods | Moderate to high for short-term contact | Not normally intended for oven use; wax can soften or transfer at elevated temperatures | Cold sandwiches, cheese, confectionery, bakery items, deli products | Useful for release and grease control; confirm wax composition, odor, migration, and market-specific restrictions | Coating may prevent conventional recycling; compostability claims require recognized certification and facility compatibility |
| Water-Based Dispersion-Coated Paper | Paper with a water-based barrier coating, such as acrylic or other polymer dispersion | 45–120 g/m² | Moderate to high, depending on coating formulation | Moderate to high | Some grades tolerate hot filling or warm food; verify sealing and temperature performance | Takeaway wraps, bakery packs, snack pouches, food-service sheets and bags | Can provide a balance of grease and moisture resistance; ask for repulpability, coating weight, and food-contact declarations | Some grades are designed for paper recycling, but actual acceptance depends on coating and regional mill capability |
| Polyethylene-Coated Paper | Paper laminated or extrusion-coated with polyethylene | 60–180 g/m² | High | High | Suitable for many cold and warm applications; confirm maximum temperature and direct-food-contact limits | Frozen foods, liquid-containing foods, quick-service wraps, cups, trays, and grease-resistant packaging | Strong barrier and heat-sealing performance; check local rules on plastic-containing paper and extended producer responsibility fees | Usually more difficult to recycle as paper because of the plastic layer; requires compatible collection and reprocessing |
| Aluminum-Foil Laminated Paper | Paper laminated with a thin aluminum foil layer, sometimes with additional sealant | 70–200 g/m² | Very high | Very high; provides strong light, oxygen, and aroma protection | Can support hot-fill or retort-related uses only when the complete laminate is specifically qualified | Chocolate, coffee, powdered foods, fatty foods, aroma-sensitive products, and long-shelf-life applications | Select when barrier performance outweighs simplicity; confirm seal strength, pinhole resistance, migration data, and import requirements | Generally not suitable for ordinary paper recycling because it is a multi-material laminate |
| Wet-Strength Paper | Paper containing wet-strength additives to retain strength when damp | 50–150 g/m² | Low to moderate unless additionally treated | Moderate to high strength retention; not necessarily waterproof | Suitable for chilled or damp handling; oven use depends on the specific grade | Fresh produce, meat and seafood interleaves, chilled foods, food-service liners, damp products | Reduces tearing during handling; verify wet-strength chemistry, absorbency, odor, and food-contact compliance | Recyclability can be reduced by wet-strength additives and food contamination; follow local mill requirements |
