Industrial and Commercial Paper Products: Printing, Wrapping, Packaging and Dunnage Guide
From books and printed documents to protective packaging and food wrapping, different paper grades are engineered for different purposes.
Although these products all belong to the broad paper category, their properties and intended applications can be very different.
Uncoated Paper and Coated Paper are commonly associated with printing and communication applications, while Cultural Paper is a broad commercial term that can encompass paper used for publishing, writing and printed materials in some markets.
## Introduction to Commercial Paper
Some papers are designed for high-quality printing, while others prioritise strength, absorbency, barrier properties or economical packaging performance.
Manufacturers can control properties through fibre selection, refining, sheet formation, pressing, drying, sizing, coating, calendaring and other production steps.
The specification should reflect those differences.
## How Paper Is Made
Paper manufacturing generally begins with a suitable fibre furnish that is prepared and dispersed in water.
Coating can create a different printable surface on selected papers.
The final paper may be supplied in large reels, smaller rolls or sheets.
## Uncoated Paper
Its exposed fibre-based surface can provide a natural appearance and tactile character.
The term uncoated alone does not define every performance characteristic.
These differences affect both appearance and print behaviour.
## Why Choose Uncoated Paper?
Its tactile character can also be desirable for certain publications and printed materials.
Ink can penetrate the sheet differently depending on sizing and porosity.
Some grades prioritise writing characteristics, while others are optimised for particular printing processes.
## Printing on Uncoated Paper
Books, manuals, forms and stationery are examples of applications that can use appropriate uncoated grades.
Ink behaviour should be considered when designing for Uncoated Paper.
Basis weight and paper construction can influence this characteristic.
## Understanding Coated Paper
Coated Paper has a surface layer formulated to modify characteristics such as smoothness, ink holdout and print appearance.
The word coated covers multiple technologies.
Magazines, brochures, catalogues and promotional materials can use coated grades.
## High-Sheen Coated Paper
This can support vivid visual presentation in suitable printing applications.
Lighting and reading conditions can influence the desired finish.
Finishing operations such as folding and binding should also be considered.
## Matte Paper Finishes
Specific surface appearance varies by manufacturer.
Matte finishes are used in publications, brochures and other printed materials where a subdued appearance is desired.
Matte does not necessarily mean completely non-reflective.
## Comparing Coated and Uncoated Paper
This difference influences printing behaviour, texture and appearance.
The project determines which characteristics are preferable.
Cost, print method, finishing and end use should also be considered.
## What Is Cultural Paper?
Cultural Paper is a commercial term used in some paper markets for grades associated with cultural communication, publishing, writing and printing applications.
Products described as Cultural Paper may include paper intended for books, notebooks, educational materials, office printing or other communication uses.
The intended printing process and finished publication influence material choice.
## Paper for Books and Printed Publications
Books with extensive text can have different requirements from highly illustrated publications.
Adequate opacity can reduce distracting show-through.
Bulk can also influence the physical feel of a finished book.
## Writing and Office Paper
Suitable Cultural Paper grades can be used for writing, office communication and educational applications.
Individual grades behave differently.
Paper should be appropriate for the intended printer or copier.
## Choosing Paper for Publishing
Book paper should be selected according to the type of publication.
Illustrated books may place greater emphasis on image reproduction.
Printers can advise on appropriate sheet planning.
## Paper Basis Weight and GSM
A higher GSM generally indicates more mass per unit area, but it does not by itself describe every physical characteristic.
Both GSM and caliper may therefore matter.
Printing, wrapping and protective packaging can require very different paper weights.
## Understanding Paper Caliper
It should not be confused directly with basis weight.
It can also affect packaging and converting processes.
Application requirements should allow for appropriate variation.
## Choosing Paper Colour Characteristics
Different measurement systems can also be used.
Designers may therefore evaluate physical samples under appropriate lighting.
The appropriate appearance is project-specific.
## Why Paper Opacity Matters
Opacity describes how effectively paper limits the visibility of material from the opposite side.
The required level depends on the finished product.
Technical data and print testing can support selection.
## Paper Smoothness
Surface smoothness influences contact between paper and printing systems.
Calendaring and other finishing processes influence the result.
Samples can help demonstrate these differences.
## Printing Behaviour of Paper
Paper structure influences how ink remains on or penetrates the surface.
Actual behaviour depends on the individual grade and press conditions.
Printing parameters should therefore be adjusted for the stock being used.
## Dunnage Paper
The exact protective performance depends on paper and package design.
Dunnage Paper can be supplied in rolls, sheets or formats intended for use with converting equipment.
Weight, fragility, package dimensions and transportation conditions should be considered.
## Protective Paper Packaging
The required amount and configuration vary.
Packaging performance should reflect foreseeable distribution conditions.
The outer box and closure method also contribute to protection.
## Void Fill Paper
Void fill is used to occupy unnecessary empty space within a package and help limit product movement.
Excessive empty space can allow items to move during handling.
Efficient package sizing can reduce the amount of void fill required.
## Protective Paper for Impact Management
Performance depends on material, conversion geometry and package design.
A packaging solution should be designed according to the risks expected during distribution.
Corners, edges and vulnerable surfaces may require particular attention.
## Wrapping Products for Shipping
Wrapping can help separate surfaces and provide a degree of abrasion protection.
Items with delicate finishes may require a paper surface that will not damage them.
The complete package should be designed for anticipated handling.
## Paper and Plastic Protective Packaging
No single material is ideal for every shipment.
Plastic systems can have different weight, moisture and cushioning characteristics.
Material source, quantity, reuse and end-of-life options all matter.
## Food Wrapper
Paper-based Food Wrapper products can be used for a variety of foods when their material construction is suitable.
Moisture, grease and temperature can all matter.
Food-contact compliance should be confirmed for the specific material and intended conditions of use.
## Food Wrapper for Dry Foods
The required material depends on the product and expected storage conditions.
The packaging system should be selected around actual product behaviour.
Food-contact considerations extend beyond the base paper alone.
## Food Wrapping for Greasy Products
Ordinary paper may not provide the required performance.
Grease resistance can be achieved through different paper-making, treatment or barrier approaches.
Contact time, food temperature and grease level can influence performance.
## Paper and Moisture Protection
Moisture can weaken or change the behaviour of some paper materials.
Surface treatments or additional layers can modify moisture interaction.
End-use conditions matter.
## Food-Contact Paper Safety
Paper intended for direct food contact should meet applicable requirements for the intended market and application.
Material suitability should be established before use.
A wrapper for room-temperature dry food may have different requirements from packaging exposed to hot or fatty food.
## Printing on Food Wrapper Materials
Food Wrapper can be printed with branding, patterns or product information when the packaging construction and printing system are appropriate.
Generic commercial printing inks should not automatically be assumed suitable for every food package.
Print quality also depends on the wrapper surface.
## Coated Paper for Packaging
Different products can use very different coating systems.
A printing coating should not automatically be assumed to provide moisture, grease or other barrier performance.
Packaging specifications should therefore identify the required function.
## Coatings and Barrier Properties
Their chemistry and application methods vary.
A single coating may not provide every type of barrier.
Some coated papers can be compatible with established paper recovery systems, while others may require different handling.
## Recycling Coated Paper
Conventional mineral-pigment coated printing papers can differ substantially from papers with polymeric or complex barrier layers.
Some paper mills can process certain coated papers within normal fibre streams.
Accurate recycling claims should reflect the actual paper construction and available collection and processing infrastructure.
## Uncoated Paper and Sustainability
Broad assumptions can be misleading.
Recycled fibre can also be appropriate for many products.
A well-designed product can use enough paper to perform its function without excessive consumption.
## Paper Supply Formats
High-volume automated operations frequently use rolls, while sheet formats can suit many printing and manual applications.
Printing papers are commonly available in both sheet and web formats.
Sheet dimensions and grain direction can matter for printing and converting.
## Paper Converting
Processes can include slitting, sheeting, cutting, folding, creasing, printing and other operations.
Dunnage Paper can be converted during use into cushioning or void-fill structures.
Stiffness, grain direction, coating and thickness can affect folding or feeding.
## Choosing Paper for Printing
A paper suitable for one process should not automatically be assumed ideal for another.
Surface energy, moisture, smoothness and absorbency can influence printing behaviour.
A proof on the intended paper provides more meaningful information than viewing a design Dunnage Paper only on a screen.
## How to Store Paper Correctly
Storage conditions should therefore be managed appropriately.
Specific manufacturer recommendations should be followed.
Sudden environmental changes can affect paper behaviour.
## Managing Paper in Production
Paper exchanges moisture with its surrounding environment.
Very dry or humid conditions can create different production challenges.
Packaging paper used in distribution may encounter changing environments after conversion.
## How to Specify Paper Packaging
A broad packaging-paper label is not enough for detailed specification.
Many projects require a balance of several characteristics.
Paper needs to run effectively through the equipment used to transform or apply it.
## Paper Selection for Printed Communication
The best paper supports the complete publication.
Cultural Paper encompasses a broad range of communication-related grades in some markets.
Paper should provide the required performance without unnecessary specification.
## Choosing Food Wrapping Paper
Storage duration and handling should also be considered.
Printing, coatings and adhesives can also form part of the food-contact evaluation.
Performance and safety requirements should remain the priority.
## How to Specify Paper Dunnage
Dunnage Paper should be selected according to the item being protected and the distribution environment.
Packaging design should therefore consider the finished cushioning structure.
Appropriate testing should reflect the risks relevant to the distribution system.
## Custom Paper Products
Paper can be customised through dimensions, printing, coating and converting according to application requirements.
Custom Dunnage Paper may be supplied in dimensions compatible with particular packaging equipment.
Material, dimensions, tolerances, printing and compliance requirements can all be relevant.
## Testing Paper Products
These can include basis weight, thickness, moisture, strength, surface or optical characteristics depending on the grade.
Printing papers may emphasise surface and optical properties.
Performance should be measured against the requirements of the finished product.
## What to Ask a Paper Supplier
Product names alone may not provide enough information.
For Dunnage Paper, discuss packaging equipment and protection requirements.
Roll dimensions, sheet sizes, packaging and delivery requirements should be established.
## Common Paper Selection Mistakes
The complete specification should reflect the application.
Another mistake is assuming that all Coated Paper has the same coating.
General printing paper should not automatically be substituted.
The outer container, product positioning and cushioning design all contribute to packaging performance.
Finally, broad sustainability claims should be treated carefully.

## Understanding Paper for Printing, Packaging and Food Wrapping
Paper may appear to be a simple material, but commercial paper products can be engineered for substantially different functions.
Individual uncoated papers can still differ substantially in smoothness, opacity, shade, bulk and print behaviour.
In packaging, other coating technologies can provide different functional properties, so the exact coating should always be identified.
Because the term can encompass multiple grades, the individual specification remains important.
Its effectiveness depends on paper grade, conversion method and the complete packaging system.
Grease, moisture, temperature and contact duration can influence requirements.
Different applications prioritise different combinations of these characteristics.
The printing process should be matched to the substrate.
Environmental considerations require equally careful evaluation.
Define the required printing, protection, food-contact, converting and appearance characteristics before selecting the grade.
