Polythene Postal Bags: A Versatile Packaging Solution for Your Mailing Needs

Polythene postal bags, also known as polymailers or mail sacks, have become an indispensable part of the modern postal system. These versatile packaging solutions offer a convenient and cost-effective way to send a wide variety of items through the mail.

Features and Benefits of Polythene Postal Bags

Polythene postal bags are made from a robust polythene material that provides excellent protection for enclosed items. They are typically closed using a peel-and-seal strip, making them easy to open and close for both senders and recipients.

Durability and Protection: Polythene postal bags are highly durable and can withstand the rigors of postal handling. They are resistant to tearing, punctures, and moisture, providing excellent protection for delicate or fragile items.

Waterproofing and Weather Resistance: Polythene’s waterproof properties make it ideal for mailing items that may encounter rain or other wet conditions. This is particularly important for items that contain documents, photographs, or other moisture-sensitive materials.

Versatility and Size Selection: Polythene postal bags come in a wide variety of sizes to accommodate different types of items and mailing needs. From small delicate items to large bulky parcels, there is a polymailer size to fit every requirement.

Transparency and Opaqueness: Polythene postal bags can be either transparent or opaque. Transparent bags allow the recipient to easily see the contents without opening the bag, while opaque bags provide extra privacy and security for sensitive items.

Cost-Effectiveness: Polythene postal bags are relatively inexpensive, making them a cost-effective packaging solution for businesses of all sizes.

Environmental Considerations: While polythene is a petroleum-based material, there are increasing efforts to produce eco-friendly polythene postal bags using recycled materials and recyclable components.

Applications of Polythene Postal Bags

Polythene postal bags are used for a wide variety of mailing purposes, including:

  • Sending documents and paperwork: Polythene bags provide a secure and moisture-resistant way to mail sensitive documents, such as contracts, invoices, and confidential records.
  • Shipping merchandise and products: Polythene bags are commonly used for shipping e-commerce orders, small business products, and retail items.
  • Sending gifts and packages: Polythene bags are a convenient and stylish way to mail gifts and packages, especially for items that need extra protection.
  • Sending bulky or awkward items: Polythene bags can accommodate bulky or awkwardly shaped items, such as books, CDs, or electronic devices.

Choosing the Right Polythene Postal Bag

When selecting a polythene postal bag, consider the following factors:

  • Item size and weight: Choose a bag that is large enough to accommodate the item without being too bulky or heavy.
  • Material thickness: The thickness of the polythene material determines its durability and waterproofing. Choose a thicker gauge for heavier or more delicate items.
  • Sealing mechanism: Peel-and-seal bags are the most common type, but they may not be suitable for larger or heavier items. For more secure closures, consider bags with adhesive tape or zip-top closures.
  • Transparency or opacity: Choose clear bags for items that need to be seen, or opaque bags for more privacy or security.


Polythene postal bags have revolutionized the way we mail items, offering a convenient, cost-effective, and versatile packaging solution for a wide variety of applications. As businesses and consumers become more environmentally conscious, eco-friendly polythene alternatives are gaining popularity, making these bags an even more sustainable and responsible choice for mail and shipping.
