GSM Is a Mechanical Specification – Not a Quality Score<\/strong><\/p>\nGSM describes the mass of paper per square meter. It influences body, handling, stiffness, material consumption and, within the same grade, often mechanical robustness. It does not by itself define non-stick release, grease barrier or oven suitability.<\/p>\n That is why “higher GSM = better paper” is a poor purchasing rule. A lighter grade may be the correct choice for a small perforated liner, while a larger bowl-shaped liner or high-load bakery process may need more body. The correct range depends on geometry and process stress.<\/p>\n \n\n\n| \n GSM Decision Factor<\/strong><\/p>\n<\/td>\n| \n Why It Matters<\/strong><\/p>\n<\/td>\n<\/tr>\n\n| \n Size \/ exposed area<\/p>\n<\/td>\n | \n Larger unsupported areas can need more body or better shape control<\/p>\n<\/td>\n<\/tr>\n | \n| \n Finished shape<\/p>\n<\/td>\n | \n Deep or bowl-shaped forming introduces creases and localized stress<\/p>\n<\/td>\n<\/tr>\n | \n| \n Stiffness \/ handling<\/p>\n<\/td>\n | \n Affects feeding, stacking, picking and position retention<\/p>\n<\/td>\n<\/tr>\n | \n| \n Tear strength<\/p>\n<\/td>\n | \n Important when users lift the liner with hot or greasy food<\/p>\n<\/td>\n<\/tr>\n | \n| \n Perforation<\/p>\n<\/td>\n | \n Open area removes material and can lower local mechanical strength<\/p>\n<\/td>\n<\/tr>\n | \n| \n Material efficiency<\/p>\n<\/td>\n | \n Excess GSM adds cost and weight without necessarily solving release or grease problems<\/p>\n<\/td>\n<\/tr>\n | \n| \n Converting line<\/p>\n<\/td>\n | \n Die cutting, folding, forming and winding all respond to paper structure, not GSM alone<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n 8. Heat Resistance: Ask for Temperature + Time + Use Condition<\/strong><\/p>\nA single maximum-temperature number is not a complete heat specification. Paper performance can change with exposure time, food load, moisture, hot oil, airflow, proximity to heating elements and whether the paper is used flat or in a formed liner.<\/p>\n Before mass production, define the real operating window and ask the supplier to confirm that the exact grade is intended for it. Then reproduce that condition during sample testing.<\/p>\n \n- Normal operating temperature and maximum expected temperature.<\/li>\n
- Typical and maximum exposure time.<\/li>\n
- Dry heat, steam, hot oil or mixed food contact.<\/li>\n
- Loaded versus unloaded condition.<\/li>\n
- Expected visual changes: browning, curl, brittleness or shrinkage.<\/li>\n
- Release and tear performance after heating, not only before heating.<\/li>\n<\/ul>\n
For Sure Paper’s current silicone-coated baking-paper range, selected grades are specified up to 230°C. This should be treated as a grade-specific product rating, not as a universal claim for every silicone or greaseproof paper.<\/p>\n 9. Perforation, Curl and Finished Geometry<\/strong><\/p>\nFor air fryer paper and other die-cut liners, converting design can be just as important as the base material. Perforations help manage airflow and drainage, but they also remove material and create stress concentration points. A pattern with too much open area can tear during handling even when the raw paper has acceptable strength.<\/p>\n \n\n\n| \n Perforation Parameter<\/strong><\/p>\n<\/td>\n| \n What to Specify<\/strong><\/p>\n<\/td>\n<\/tr>\n\n| \n Hole diameter<\/p>\n<\/td>\n | \n Target size and tolerance where critical<\/p>\n<\/td>\n<\/tr>\n | \n| \n Spacing<\/p>\n<\/td>\n | \n Center-to-center spacing or approved drawing<\/p>\n<\/td>\n<\/tr>\n | \n| \n Pattern \/ orientation<\/p>\n<\/td>\n | \n Repeat pattern and direction relative to the liner shape<\/p>\n<\/td>\n<\/tr>\n | \n| \n Open area<\/p>\n<\/td>\n | \n Total perforated area where airflow performance matters<\/p>\n<\/td>\n<\/tr>\n | \n| \n Edge distance<\/p>\n<\/td>\n | \n Minimum distance between perforation and die-cut edge<\/p>\n<\/td>\n<\/tr>\n | \n| \n Hole quality<\/p>\n<\/td>\n | \n Clean cuts without excessive tearing or fiber pull<\/p>\n<\/td>\n<\/tr>\n | \n| \n Forming \/ crease lines<\/p>\n<\/td>\n | \n Ensure holes do not create weak points at folds or corners<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Curl is another finished-product issue. It can be influenced by moisture balance, coating differences between sides, paper structure, storage and heat exposure. For formed liners, evaluate flatness before use, stability during cooking and shape retention after the full cycle.<\/p>\n ![\"air-fryer-liner-perforation-design.png\"](\"https:\/\/ecdn6.globalso.com\/upload\/p\/978\/image_other\/2026-09\/air-fryer-liner-perforation-de.png\") <\/p>\n
Food-contact approval should be linked to the exact material structure being purchased. A generic “food grade” statement is not enough when the order includes a specific base paper, silicone coating, printing ink, adhesive or other converting material.<\/p>\n State the destination market and intended use before mass production so the supplier can provide the relevant documentation. Depending on the market and product, this may involve food-contact frameworks such as FDA requirements in the United States, EC 1935\/2004 and applicable European\/national requirements, or other destination-specific standards.<\/p>\n PFAS-free should also be treated as a separate requirement. It describes chemical composition or the absence of intentionally added PFAS; it does not prove non-stick release, grease holdout, heat resistance or recyclability.<\/p>\n \n- Request documents for the exact grade and coating system, not a generic supplier certificate.<\/li>\n
- Define whether printing inks, adhesives or laminations are part of the finished food-contact article.<\/li>\n
- Keep PFAS-free, food-contact compliance and functional performance as separate approval items.<\/li>\n
- Avoid broad claims such as “recyclable” or “compostable” without confirming the relevant grade, certification and local end-of-life infrastructure.<\/li>\n<\/ul>\n
11. Printing, Converting and Packaging Requirements<\/strong><\/p>\nMaterial performance can change after printing and converting. A paper that passes a raw-sheet test can still fail after heavy ink coverage, folding, scoring, perforation or forming. For private-label and high-speed converting projects, the commercial specification should therefore include process requirements as well as paper properties.<\/p>\n \n- Printing side, process, ink system and artwork coverage.<\/li>\n
- Ink adhesion, rub\/scuff resistance and set-off in stacks or rolls.<\/li>\n
- Roll width, core ID, maximum OD, winding direction and roll-edge quality.<\/li>\n
- Sheet size, die-cut tolerance, corner radius, perforation and stacking requirement.<\/li>\n
- Formed-liner height, crease design and nesting\/denesting performance.<\/li>\n
- Retail pack count, inner bag, carton, barcode, label and pallet configuration.<\/li>\n
- Moisture and edge protection for ocean transport and warehouse storage.<\/li>\n<\/ul>\n
12. Buyer RFQ Checklist<\/strong><\/p>\nA clear RFQ reduces sample rounds and makes quotations easier to compare. Instead of sending only a product name and GSM, provide the operating conditions that define success.<\/p>\n \n\n\n| \n Specification<\/strong><\/p>\n<\/td>\n| \n Buyer Should Define<\/strong><\/p>\n<\/td>\n<\/tr>\n\n| \n Application<\/p>\n<\/td>\n | \n Baking sheet, cake liner, air fryer liner, food wrap, interleaving, tray liner, etc.<\/p>\n<\/td>\n<\/tr>\n | \n| \n Main failure to prevent<\/p>\n<\/td>\n | \n Sticking, grease penetration, tearing, curl\/lift, poor printing, etc.<\/p>\n<\/td>\n<\/tr>\n | \n| \n Food type<\/p>\n<\/td>\n | \n Dry, fatty, sugary, cheesy, saucy, frozen, moist, etc.<\/p>\n<\/td>\n<\/tr>\n | \n| \n Heat condition<\/p>\n<\/td>\n | \n Operating\/max temperature and exposure time<\/p>\n<\/td>\n<\/tr>\n | \n| \n Paper \/ color<\/p>\n<\/td>\n | \n White or natural brown; base-paper requirement if specified<\/p>\n<\/td>\n<\/tr>\n | \n| \n GSM<\/p>\n<\/td>\n | \n Target or acceptable range<\/p>\n<\/td>\n<\/tr>\n | \n| \n Silicone<\/p>\n<\/td>\n | \n 1S or 2S; coated side and orientation<\/p>\n<\/td>\n<\/tr>\n | \n| \n Grease resistance<\/p>\n<\/td>\n | \n Required method\/target or practical holdout condition<\/p>\n<\/td>\n<\/tr>\n | \n| \n Finished format<\/p>\n<\/td>\n | \n Jumbo roll, sheet, consumer roll, die-cut or formed liner<\/p>\n<\/td>\n<\/tr>\n | \n| \n Dimensions<\/p>\n<\/td>\n | \n Width, length, diameter, height and tolerances<\/p>\n<\/td>\n<\/tr>\n | \n| \n Roll details<\/p>\n<\/td>\n | \n Core ID, OD, winding direction, splice limit if relevant<\/p>\n<\/td>\n<\/tr>\n | \n| \n Perforation<\/p>\n<\/td>\n | \n Hole diameter, spacing, pattern, open area and edge distance<\/p>\n<\/td>\n<\/tr>\n | \n| \n Printing<\/p>\n<\/td>\n | \n Colors, coverage, print side, artwork and process<\/p>\n<\/td>\n<\/tr>\n | \n| \n Compliance<\/p>\n<\/td>\n | \n Destination market, food-contact documents, PFAS-free and other requirements<\/p>\n<\/td>\n<\/tr>\n | \n| \n Packing<\/p>\n<\/td>\n | \n Pieces\/pack, carton, pallet and private-label requirements<\/p>\n<\/td>\n<\/tr>\n | \n| \n Volume<\/p>\n<\/td>\n | \n Trial quantity plus expected monthly\/annual demand<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n ![\"baking-paper-application-test.png\"](\"https:\/\/ecdn6.globalso.com\/upload\/p\/978\/image_other\/2026-09\/baking-paper-application-test.png\") <\/p>\n
13. How to Validate Samples Before Mass Production<\/strong><\/p>\nSample approval should reproduce the real application as closely as possible. If the customer buys a perforated bowl-shaped air fryer liner, approving a flat A4 sheet from the same roll is not enough. If the product is used for greasy takeaway food for 45 minutes, a short room-temperature oil drop test is not enough.<\/p>\n \n- Confirm the material structure, GSM, coating side and dimensions against the RFQ.<\/li>\n
- Inspect coating\/surface consistency and identify the food-contact side.<\/li>\n
- Run release testing with representative food when sticking is a risk.<\/li>\n
- Run grease-holdout testing for the expected oil level, temperature and contact time.<\/li>\n
- Complete the intended oven, fryer, steaming or cooking cycle.<\/li>\n
- Check curl, lift, browning, brittleness, tearing and deformation after heating.<\/li>\n
- Test printing, die cutting, perforation, folding or forming where applicable.<\/li>\n
- Review food-contact and PFAS-free documentation for the exact commercial grade.<\/li>\n
- Approve a physical reference sample and a written commercial specification for repeat orders.<\/li>\n<\/ol>\n
Best practice for repeat orders<\/strong><\/p>\nKeep an approved reference sample together with the final specification. For future lots, evaluate the same critical functions – not only GSM and dimensions. This is especially important for release coating, grease resistance, curl and converting consistency.<\/p>\n Which One Should You Choose?<\/strong><\/p>\n\n\n\n| \n Application Need<\/strong><\/p>\n<\/td>\n| \n Recommended Starting Point<\/strong><\/p>\n<\/td>\n| \n Validation Focus<\/strong><\/p>\n<\/td>\n<\/tr>\n\n| \n Clean release is the dominant requirement<\/p>\n<\/td>\n | \n Silicone coated paper<\/p>\n<\/td>\n | \n Release after the actual heat\/contact cycle<\/p>\n<\/td>\n<\/tr>\n | \n| \n Grease penetration is the dominant risk<\/p>\n<\/td>\n | \n Greaseproof paper or a grease-resistant construction<\/p>\n<\/td>\n | \n Grease holdout at real food temperature and contact time<\/p>\n<\/td>\n<\/tr>\n | \n| \n Air fryer liner<\/p>\n<\/td>\n | \n Usually silicone-coated baking paper as a starting point, then optimize structure and design<\/p>\n<\/td>\n | \n Release, airflow, curl\/lift, perforation and heat cycle<\/p>\n<\/td>\n<\/tr>\n | \n| \n Food wrapping \/ serving<\/p>\n<\/td>\n | \n Greaseproof paper is often the more efficient starting point<\/p>\n<\/td>\n | \n Oil holdout, wet strength, printing and handling<\/p>\n<\/td>\n<\/tr>\n | \n| \n Both release and grease resistance matter<\/p>\n<\/td>\n | \n Compare complete constructions rather than material names<\/p>\n<\/td>\n | \n Finished-product application trial<\/p>\n<\/td>\n<\/tr>\n | \n| \n Cost is the main pressure<\/p>\n<\/td>\n | \n Remove functions the application does not need – do not downgrade critical performance<\/p>\n<\/td>\n | \n Total usable performance and failure cost, not only USD\/MT<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Conclusion<\/strong><\/p>\nThere is no universal winner in silicone coated paper vs greaseproof paper. They solve different primary problems. Silicone coating is about release. Greaseproof construction is about grease holdout. In real food packaging, those functions may overlap, but they should still be specified and tested separately.<\/p>\n For buyers, the most reliable approach is to define the failure that cannot be accepted, then match the paper structure, GSM, silicone side, grease requirement, heat cycle, geometry and converting process to that risk. A good supplier should be able to explain why a structure is being recommended – and what test will prove it.<\/p>\n For a technical review, send Sure Paper your application, food type, operating temperature\/time, required size or roll dimensions, GSM range, 1S\/2S requirement, perforation\/shape and expected volume.
