Polywrapping is a smart, cost-effective way to protect your mail, enhance presentation, and reduce postage costs. Widely used in direct mail fulfilment, polywrapping ensures your materials arrive securely, professionally, and ready to make an impact.


Polywrapping is the process of enclosing printed materials or products in a clear plastic film. It is one of the most versatile and efficient methods of enclosing items for mailing and distribution.
Polywrapping is one of the fastest and most reliable ways to enclose and post a wide range of printed products, including: Its flexibility makes it ideal for both high-volume mailing campaigns and more complex enclosures.
Polywrapping is commonly used for:
- Magazines
- Catalogues
- Brochures
- Books
- Multi-item direct mail packs
A typical example is the distribution of educational materials, where multiple large or mixed items need to be collated, protected, and delivered together in a single, secure pack.
Using polywrapping as part of your mail fulfilment strategy offers several key advantages:
- Reduced postage costs – polywrapped items are less bulky and often qualify for lower postal rates
- Durable and protective – keeps items secure during handling and transit
- Professional presentation – enhances the overall appearance of your mail
- Environmentally responsible options – biodegradable film available to reduce environmental impact and support your sustainability goals
- Weatherproof protection – keeps brochures, magazines, catalogues, and books clean, dry, and undamaged


Alternatives to Polywrapping
Depending on the contents and objectives of your mailing, alternative enclosing methods may be more suitable.
Shrink Wrapping
Shrink wrapping uses a thicker plastic film that is heat-shrunk tightly around the items. This method is ideal when you need to firmly secure heavier or more complex packs.
Recommended for:
- Heavy catalogues combined with brochures
- Multi-item packs requiring extra stability
- Large quantities of thin or loose sheets
Poly Bagging
Poly bagging involves manually placing items into pre-made poly bags. While mechanical collation can be used for some items, this method is particularly useful for non-standard or 3-dimensional products.
Ideal for:
- Conference or event packs
- Packs containing lanyards, pens, USB drives, stress toys, or mixed promotional items
- Items that cannot be machine enclosed
