Material and Thickness

Understanding Material Options

The quality of a polymailer can significantly impact the safety of your shipments. Common materials include:

  • Polyethylene: Lightweight and water-resistant, ideal for most general shipping needs.
  • Kraft paper: Biodegradable, offering a more sustainable option for eco-conscious businesses, but less durable in wet conditions.

Evaluating Thickness

Polymailers come in various thicknesses, typically measured in microns. A few standard thicknesses include:

  • 60 microns: Suitable for lightweight items such as clothing.
  • 75 microns: Offers better protection for fragile or heavier products.

Tip: Consider the type and weight of the items you'll be shipping when selecting the thickness of your polymailer. A heavier item will require a sturdier option.

Size and Dimensions

Choosing the Right Size

Selecting the right size of polymailer is essential to prevent damage during transit and to save on shipping costs.

  • Common Sizes: Polymailers generally range from 6" x 9" to 12" x 15".
  • Consider Item Dimensions: Ensure the polymailer has enough room for your item but isn’t too large, which may lead to unnecessary shipping costs.

Custom Sizes

If your products are unique, consider ordering custom-sized polymailers that meet your specific dimensions.

Security Features

Safety and Security

Security is paramount when shipping items. Here are some features to consider:

  • Tamper-evident seals: These help to ensure that packages have not been opened during transit.
  • Opaque design: Prevents visibility, protecting the contents from theft.

Tip: Always opt for polymailers with sufficient sealing mechanisms to ensure your shipment remains secure.

Environmental Impact

Cost Considerations

Budgeting for Polymailers

While it may be tempting to opt for the cheapest polymailer, remember that quality can affect how well packages are protected. Here’s one way to assess costs:

  • Bulk orders: Purchasing polymailers in bulk can significantly reduce per-unit costs.
  • Supplier comparisons: Obtain quotes from various providers to find the best price while considering the quality.

Common Issues and Solutions
