Tourer Blue Opaque Poly Mailers — Full Product Guide
Choosing the right mailing bag is about matching the pack to your product, your packing process, and the journey your parcels take. Tourer blue opaque poly mailers are built for straightforward, high-throughput despatch: load, peel, seal, label, and ship. Below is a practical guide to help you select and use these mailers effectively.
How It Works
Poly mailers are flexible mailing bags made from polythene film. You place the item inside, remove the release liner from the adhesive strip, and fold the flap down to seal. Once sealed, the bag forms a lightweight outer layer around the contents, ready for a shipping label.
Because the film is opaque, the contents are less visible during transit. This can be helpful for customer privacy and for reducing the appearance of high-value items.
Materials and Construction
Tourer mailers use a blue opaque polythene film specified at 55 micron (55mu). In day-to-day packing, this thickness is commonly chosen for general mailing where you want a dependable bag without unnecessary bulk.
The closure is a peel-and-seal adhesive strip. This style of closure is widely used in fulfilment operations because it is fast and consistent, helping reduce packing time compared with taping.
Choosing the Right Size (Practical Selection Tips)
When selecting a mailer size, aim for a comfortable fit rather than forcing items into a tight bag. A little extra room makes packing faster and helps the seal close neatly.
- Measure your packed item (including any inner packaging such as tissue, polybags, or bubble wrap).
- Allow space for the flap so the adhesive can fold over cleanly without strain.
- Consider irregular shapes: bulky seams, boxed corners, or folded garments may need a larger option than flat measurements suggest.
- Standardise where possible: choosing a small set of sizes can simplify picking and reduce packing errors.
Note: This product page may cover multiple size/pack options within the same Tourer blue opaque mailer range. Select the option that best matches your application.
Floor Type Compatibility
These mailers are suitable for typical warehouse and packing environments. For best results, store and use them in a clean, dry area so the adhesive strip remains free from dust and fibres. If your packing area is particularly cold, allow mailers to acclimatise to room temperature to support consistent sealing performance.
Health and Safety
- Keep away from children: plastic bags can present a suffocation hazard.
- Use cutting tools carefully: if opening returned parcels or trimming labels, follow site safety procedures.
- Adhesive handling: avoid touching the adhesive strip excessively to maintain seal quality.
Ideal Applications and Use Cases
Tourer blue opaque poly mailers are best suited to items that do not require rigid protection but do benefit from a protective outer wrap and discreet presentation.
- Fashion & apparel: t-shirts, hoodies, trousers, and other folded garments.
- Soft goods: textiles, linens, and non-fragile accessories.
- General ecommerce: everyday parcels where weight and packing speed matter.
- Returns processing: useful as an outbound pack where customers may re-use packaging (depending on your returns policy and how you instruct customers).
Maintenance, Cleaning and Care
Poly mailers are designed for single-use shipping. To keep them performing well before use:
- Store flat to prevent creasing and to keep the flap aligned.
- Keep dry and dust-free so the peel-and-seal adhesive remains effective.
- Avoid heat sources and prolonged direct sunlight during storage.
Packing Best Practices (For a Better Customer Experience)
- Use an inner bag for small parts: if shipping items with loose components, place them in an inner pouch first.
- Protect sharp edges: corners or sharp packaging can stress the film; add an inner layer if needed.
- Apply labels to a smooth area: press firmly to ensure good adhesion and scan reliability.
- Seal once, seal well: align the flap carefully and apply even pressure along the adhesive strip.
Case Study (Example Workflow)
Scenario: A small ecommerce clothing brand ships daily orders with a two-person packing team.
