Technical, Barrier, Recycled and Envelope Papers
Technical and specialty papers are a group of materials used in production, packaging, converting, printing, logistics and industrial applications. They include base papers for further processing, recycled materials, liners, offset papers, barrier papers, coated papers, waterproof, greaseproof and envelope papers.
This is a consolidated page for materials that are often selected not by their trade name but by their function in the process: printing, packaging, interleaving, sheeting, rewinding, envelope production, moisture protection, grease resistance or further processing.
When to Choose Technical and Specialty Papers?
Technical papers are worth choosing when standard packing paper, office paper or sheet paper does not meet the process requirements. This applies especially to materials intended to perform a specific production, protective, barrier, printing or converting function.
Most common applications:
- packaging production,
- sheeting and rewinding,
- further paper processing,
- envelope production,
- technical packaging,
- product interleaving and separation,
- protection against moisture or grease,
- preparing material for printing,
- production of auxiliary materials,
- work on production lines,
- converting for the customer’s process.
Material Range
| Material group | Examples | Application |
|---|---|---|
| Recycled papers | recycled paper, grey, testliner | interleavers, packaging, sheeting, production |
| Kraft and liner papers | kraft, kraftliner, White Kraftliner, Liner Lux | packaging, interleavers, protection, envelopes |
| Offset papers | white offset, printing papers | printing, sheets, office material production |
| Barrier papers | PE, waterproof, greaseproof | packaging, protection against moisture and grease |
| Coated papers | coated and specialty | printing, packaging, technical applications |
| Envelope paper | offset, kraft, testliner | envelope and paper packaging production |
| Industrial papers | technical, interleaving, protective | production, warehouse, packaging, service |
Recycled Papers and Testliner
Recycled papers and testliner are used in processes where technical function, material economy and further processing potential matter. They can be used as interleavers, packaging, sheeting, production materials or product protection.
Typical applications:
- paper interleavers,
- protective layers,
- technical packaging,
- bulk packaging,
- materials for further processing,
- work sheets,
- production of packaging components.
Kraft Papers, Kraftliner, White Kraftliner and Liner Lux
Kraft papers and liners are chosen where strength, packaging function, further processing capability or surface aesthetics are important. They can be used in packaging production, interleavers, envelopes, protection and technical materials.
| Material | When to choose | Typical application |
|---|---|---|
| Kraft paper | universal packaging and product protection | rolls, sheets, interleavers, wrapping |
| Kraftliner | packaging, technical materials, production | packaging layers and protection |
| White Kraftliner | when a lighter surface is needed | packaging, printing, more aesthetic materials |
| Liner Lux | packaging and technical applications | selection based on batch and process requirements |
| Testliner | economical packaging applications | interleavers, production, protection |
Offset Papers
Offset paper is used in printing, office material production, sheeting, printing and further processing. It can be supplied in sheets or reels, depending on the method of use.
It works well for:
- printing,
- sheeting,
- office material production,
- form production,
- envelope production,
- printing applications,
- further cutting and converting.
PE Barrier, Waterproof and Greaseproof Papers
Barrier papers are chosen where ordinary paper is insufficient. They can provide protection against moisture, grease, dirt or other factors, depending on the variant and material properties.
| Type of barrier paper | When to consider | What to determine before ordering |
|---|---|---|
| PE barrier paper | when a barrier layer is needed | type of barrier, use side, product contact |
| Waterproof paper | when material may contact moisture | resistance level and working conditions |
| Greaseproof paper | when grease penetration is a concern | application, contact time and packaging method |
| Coated paper | when a modified surface is required | coating type, printing, processing |
| Barrier technical paper | non-standard production conditions | parameters confirmed individually |
For barrier papers, describing the application is particularly important. Different parameters are needed for packaging, interleaving, further processing or packaging production.
Coated and Technical Papers
Coated papers can be used in printing, packaging, production of utility materials and processes requiring a specific surface. The coating can affect aesthetics, protective function, printability or material resistance.
Typical applications:
- printing,
- packaging,
- promotional materials,
- technical items,
- interleavers with specific surface,
- further processing,
- utility material production.
Envelope Paper
Envelope paper should be selected based on production technology, expected strength, appearance, grammage, printing method and further processing. Depending on the application, offset, kraft, testliner or other materials can be considered.
When selecting envelope paper, determine:
- paper type,
- grammage,
- color,
- surface,
- format or reel width,
- whether the material will be printed,
- whether it will be cut, creased or glued,
- required batch consistency.
Delivery Forms of Technical Papers
Specialty papers can be supplied as sheets, rolls, reels or material for further processing. The choice of form depends on whether the paper will be used directly or undergo another production operation.
| Form | When to choose | Main benefit |
|---|---|---|
| Sheets | when the process requires a repeatable format or ready interleavers | quick retrieval and use |
| Rolls | when material will be used at a packaging or protection workstation | flexible material length |
| Reels | when paper goes to further production or machine work | input material for process |
| Blanks | when a ready dimension for manual or semi-automatic process matters | operation standardization |
| Production batches | when material is selected for a specific order | matching customer process |
How to Choose a Technical or Specialty Paper?
Technical paper selection should start with the process in which the material will be used. The paper name alone is insufficient if it is not known whether the paper will be printed, cut, glued, rewound, sheeted, used as an interleaver or serve a barrier function.
Key parameters:
-
End use
Determine whether the paper will be used for packaging, production, printing, envelopes, interleavers, protection or further processing. -
Material type
Options may include recycled papers, kraft, liners, offset, coated, barrier or technical papers. -
Grammage
Grammage affects stiffness, strength, weight, protective function and further processing capability. -
Delivery form
Sheet, roll, reel or blank should match the machine, workstation or customer process. -
Special properties
For barrier papers, specify resistance to moisture, grease, dirt, coating type or use side. -
Further processing
Indicate whether the paper will be printed, cut, sheeted, rewound, creased, glued or converted. -
Consistency and quantity
For recurring production, establish tolerances, batch availability and expected demand.
Technical Papers for Production and Converting
In production and converting, technical papers serve as input material, protective, interleaving or auxiliary material. They can be used in the form of reels, rolls, sheets or blanks.
They work well for:
- sheeting,
- rewinding,
- cutting to format,
- interleaver production,
- packaging production,
- envelope production,
- technical packaging,
- preparing auxiliary materials,
- printing processing,
- paper converting.
Technical Papers for Packaging and Protection
Technical papers can serve a protective function in packaging, warehousing and transport. Depending on the material, they can protect surfaces, separate products, limit soiling or provide protection against selected factors.
Example applications:
- interleavers between products,
- protective sheets,
- wrapping paper,
- packaging lining paper,
- surface protection paper,
- technical product packaging paper,
- internal transport paper,
- parts storage paper.
