You need strong paper for tough jobs because it does not tear easily and stays strong under pressure. Durability and weight are important when you pack, print, or keep valuable things safe. Kraft paper is known for being tough and good for the environment.
More companies want sturdy paper as they move to greener packaging.
The world market for paper and paperboard packaging was $381.4 billion in 2024 and may reach $620.6 billion by 2034, with food, drink, and online shopping leading the way.
Paper weight changes how well your packaging or printed things work. Picking the right thickness or strength helps your project do well.
Pick strong paper for tough jobs so it lasts longer and does not rip. Kraft paper is a great pick because it is strong and good for the environment.
Learn about paper weight, which is measured in GSM, to pick the right thickness for your work. If the GSM is higher, the paper is stronger and lasts longer.
Think about how tough the paper is and how it is tested to make sure it can handle rough use every day. Find paper with high tensile and tear resistance.
Use the right paper for what you need. Chipboard works well for dividers, cotton paper is good for important papers, and kraft paper is best for packing heavy things.
Always look at the paper weight guide before you buy. This helps you not make mistakes and makes sure you get the best paper for your job.
When you pick paper for hard jobs, you should know what makes it strong. Strong paper does not break or rip easily. It can hold heavy things without falling apart. Two main things help you check this: tensile strength and tear resistance. Tensile strength means how much pulling the paper can take before it snaps. Tear resistance means how well the paper stops a rip from getting bigger. These things are important if you want your packaging or printed stuff to last a long time.
Here is a quick look at the main properties:
| Property | Definition | Application Context |
|---|---|---|
| Tensile Strength | Resistance to being pulled apart or stretched under tension. | Ropes, cables, structural components. |
| Tear Strength | Resistance to the propagation of a tear once it has started. | Packaging, apparel, upholstery. |
You should also think about fracture toughness. This tells you how much energy the paper can take before a small flaw gets worse. If you use paper with high fracture toughness, your packaging will not break easily. Even if it gets a small cut, it will still work well.
There are many types of strong paper you can pick. Each kind has special features and best uses. Here is a table to help you compare some common types:
| Type of Paper | Characteristics |
|---|---|
| Car Liner Paper | Heavy paper made from kraft pulp or waste paper stock, used for lining freight cars. |
| Check or Cheque Paper | Durable paper for bank checks, reacts to ink eradicators, shows stains with certain chemicals. |
| Chipboard | Thicker than cardboard, used for backing sheets and box partitions. |
| Cotton Paper or Rag Paper | Contains at least 25% cotton fiber, known for its durability. |
| Cover Paper or Cover Stock | Fairly heavy, used for book and brochure covers, folds well. |
| Vulcanizing Paper | Chemically treated for hardness and density, used in insulation and building materials. |
Kraft paper is a great choice for tough jobs. You see it in food packaging, shipping, and factories. Kraft paper is stronger than many other papers, like butcher paper. It does not tear easily and can hold heavy things. This makes it good for wrapping, bagging, and making boxes. You can also recycle kraft paper, which is good for the planet.
Tip: If you want to help the environment, pick strong paper that you can recycle and that breaks down naturally. Many companies now use heavy papers made from recycled stuff to make less trash.
New ways to make strong paper give you more choices. Makers now use green materials and layers to make paper stronger and better for the earth. Special paper cores and biodegradable cores help you pack and ship things safely while being eco-friendly.
When you pick strong paper, match the type to your job. Use chipboard for box dividers, cotton paper for important papers, and kraft paper for heavy things. This helps you get the right mix of strength, toughness, and being green.
There are different ways to test how tough paper is. These tests show if paper can handle folding, tearing, and daily use. Here is a table with some common tests:
| Method | Description | Sample Requirements | Turnaround Time |
|---|---|---|---|
| Köhler-Molin | Folds paper until it breaks to check endurance. | Five A4 sheets, max 0.25 mm | 3 weeks |
| Lhomargy | Repeats folding to measure how long paper lasts. | Five A4 sheets, max 0.25 mm | 3 weeks |
| MIT | Tests folding under a steady load. | Five A4 sheets, max 0.25 mm | 3 weeks |
| Schopper | Uses a special device to measure folding endurance. | Five A4 sheets, max 0.25 mm | 3 weeks |
Tear tests help you know how much force rips paper.
Elmendorf Tear Test uses a swinging arm to check tearing strength.
Trapezoidal Tear Test pulls a shaped piece along a notch.
Look for paper tested with official rules. The Schopper double fold tester uses BS ISO 5626. This rule helps you get good results. Here is a table:
| Method | Description | Standards |
|---|---|---|
| Schopper double fold tester | Measures how many times paper can fold before breaking. | BS ISO 5626 |
This test is used for money paper, maps, and wrapping paper. These rules help you compare kraft paper and other strong papers.
Durability ratings are important for packaging and work jobs. You want your packaging to last through shipping and handling. Some tests match real-life needs:
| Phase | Description | Relevance to Real-World Performance |
|---|---|---|
| Phase 1 | Micro-Indentation Measurements | Shows how packaging resists cuts from tools. |
| Phase 2 | Scratch Tests | Checks how paper holds up during handling and storage. |
| Phase 3 | Reuse Wear and Washing-Mimicking Experiment | Tests how packaging survives repeated use and cleaning. |
If you pick paper with high durability, your products stay safe and look nice longer. You can trust strong paper for heavy-duty packaging, especially kraft paper for hard jobs.
Paper weight is often shown as GSM. GSM means grams per square meter. This number tells you how heavy and thick the paper is. If you need strong paper for hard jobs, pick a higher GSM. Thicker paper is stronger and lasts longer. It works well for packaging that must hold heavy things, like boxes or cartons.
A higher GSM means the paper is thicker and heavier.
Thick paper is stronger and lasts longer.
Use higher GSM for tough packaging jobs.
Thickness is also called caliper. It shows how dense the paper is. Even thickness helps with printing and rolling. Thickness changes how strong and bulky the paper feels. It also affects how the paper looks and prints.
Tip: Always check both GSM and thickness before picking paper. These numbers help you choose the right mix of strength and quality.
It is important to know how paper weight changes how it works. Heavy paper can hold more ink and lasts longer. It is best for business cards, brochures, and strong packaging. Thicker paper stops ink from bleeding through. It also holds ink better and does not change size much when wet.
| Performance Aspect | Lightweight Paper (60-80 gsm) | Medium-weight Paper (120-180 gsm) | Heavy-weight Paper (180+ gsm) |
|---|---|---|---|
| Ink Absorption | Soaks up more ink, colors may change | Soaks up less ink, better than light paper | Soaks up the least ink, holds color best |
| Show-through | Ink bleeds through a lot | Some ink bleeds through | Almost no ink bleeds through |
| Tear Resistance | Tears easily | Tears less easily | Hard to tear |
| Drying Time | Dries fast, may smear | Dries at a medium speed | Dries slowest |
| Dimensional Stability | Changes size 3-5% in humidity | Changes size 1-3% in humidity | Changes size less than 1% |
| Longevity | Does not last long | Lasts a medium time | Lasts the longest |
