How to Choose Paper for Your Bag-Making Machine
Four specification areas decide whether a grade runs the way you expect on your bag-making line. Use them as a checklist before comparing quotations.
Basis Weight, Tensile Strength, Tear Resistance & Burst Strength
Basis weight, usually expressed in grams per square metre (GSM), is an important starting point when selecting paper for a bag, but it should not be treated as a complete measure of performance. Tensile strength, tear resistance, and burst strength provide additional information about how paper may respond to different handling and loading demands. Sure Paper’s MG/MF paper range includes grades in the 30–70 GSM range; the appropriate specification should be confirmed against the intended application and required test criteria.
Surface Smoothness & Printability
Surface characteristics influence how paper looks and performs during printing. MG paper has a highly smooth, polished side suited to detailed printing, whereas MF paper provides a more uniform finish across both sides. Consider which side will be printed, the graphics required, and the intended bag appearance when comparing available grades.
Glue Bonding & Folding Performance
A suitable paper grade needs to work with the bag’s construction and converting process, including the intended folding and adhesive operations. Surface finish and paper structure can influence processing, so manufacturers should assess bonding and folding using the adhesive, equipment, and production conditions they actually use. Sample evaluation is a practical way to identify potential compatibility issues before bulk production.
Roll Width & Machine Speed
Roll width should match the machine’s specifications and the planned bag layout to help limit avoidable trim loss. Machine speed is another factor to assess, but paper performance at a particular speed should be verified on the relevant equipment rather than assumed from the grade name. Share your required roll dimensions and production conditions with Sure Paper so the available material options can be reviewed against your needs.
Decision roles
What Matters to Your Team
Paper sourcing involves more than material selection. Procurement needs reliable supply and clear costs, production needs compatible formats, and QA needs consistent specifications and relevant documentation. Align these requirements before confirming an order.
Procurement / Owner
Paper Cost & Reliable Supply
For paper bag manufacturers, purchasing decisions involve material cost, specification suitability, and the ability to plan repeat orders.
- Comparing grades on price alone may overlook differences in surface finish, strength, coating, and converting performance.
- Sure Paper works with customers to review material requirements and order details so the quotation can reflect the requested grade and format.
Production / Converting
Will It Run on Our Bag-Making Line?
A paper grade that appears suitable on paper still needs to be checked against the customer’s equipment and production process.
- Width, basis weight, surface characteristics, folding conditions, and adhesive requirements can all influence whether a material fits the intended operation.
- Request samples and evaluate them on your bag-making line before confirming the specification for bulk purchasing.
Quality / Compliance
Consistent Quality & Specification Documentation
Clear specifications make it easier for purchasing, quality, and production teams to assess whether a paper grade meets their requirements.
- Relevant checks may include GSM, dimensions, surface characteristics, and the strength properties specified for the product.
- Sure Paper’s MG/MF product information describes quality-control checks including weight, thickness, size accuracy, and cutting precision.
- Buyers should confirm which inspection records and documents are available for their particular order.

Paper Options for Paper Bag Manufacturers
MG and MF papers differ mainly in surface finish: MG paper has one highly smooth side, while MF paper offers a more balanced finish on both sides. These characteristics provide different starting points for evaluating print quality, folding, and bag-making requirements.
Greaseproof Paper
Sure Paper's greaseproof paper is made from 100% virgin wood pulp and uses a dense paper structure to resist oil and grease without plastic coating. It is supplied for food wrapping and fast-food applications, with customizable basis weights from 30–50 GSM and flexible roll widths and sheet dimensions.
Parchment Paper
Parchment paper is designed for heat-resistant and non-stick applications such as baking, cooking, and food preparation. Sure Paper supplies silicone-coated parchment paper in roll and sheet formats, with paper weight customized from 30–100 GSM for different application requirements.
Wax Paper
Wax paper uses a wax coating to create a smooth surface and reduce moisture penetration. It is commonly used for food wrapping, snacks, and short-term food storage, supplied in 30–60 GSM weight ranges with the grade matched to the intended temperature conditions.
MG / MF Paper
MG and MF papers provide smooth surfaces and good strength for packaging and printing applications. MG generally offers greater smoothness on one side, while MF provides a practical smooth surface. Available in white or natural brown, with paper weights ranging from 30–70 GSM.
Jumbo / Slit Roll
Converters can select supply formats according to their production process, including jumbo rolls and slit rolls. Sure Paper supports customized widths and lengths for different converting requirements.
Sheet
Sheets can be supplied according to your finished format and packing requirements. Sure Paper supports customized sheet sizes for converting and food-service applications.
Material Decision Table
| Paper option | Key characteristic | What to evaluate |
|---|---|---|
| Mg white paper | Smooth, polished side | Print appearance and converting needs |
| Mf white paper | More balanced surface on both sides | Printing and folding requirements |
| Brown kraft paper | Natural brown appearance | Required strength and bag design |
| White kraft paper | Bright surface for branding | Print requirements and bag construction |
| Greaseproof paper | Intended for grease-resistance needs | Required level of grease protection |
| Pe-coated paper | Added moisture and grease barrier | Barrier requirements and end use |
Two materials can fit the same product. Confirm grade, GSM, format, and destination market with our team before final selection.
Same GSM, Different Wrapping Performance
The same GSM does not guarantee the same wrapping or baking performance. Paper type, grease resistance, coating, and heat resistance all influence material suitability. Compare the full paper specification with your intended food application instead of selecting paper by GSM alone.
| Parameter | What it actually tells you |
|---|---|
| GSM | Paper weight per square metre. It does not determine grease resistance, heat resistance, or release performance on its own. |
| Paper structure | Fiber structure and paper type affect how the paper performs in different wrapping and food preparation applications. |
| Grease resistance | Important for burger wraps, sandwich wraps, fried food liners, and other applications involving oily foods. |
| Coating & treatment | Different treatments serve different purposes. Silicone-coated parchment supports non-stick baking applications, while wax paper is used for selected wrapping needs. |
| Heat resistance | For baking and heated food preparation, confirm that the paper is suitable for the intended temperature and duration. |
| Surface & converting format | Surface properties, roll width, sheet size, and format should match printing and converting requirements. |
