Common Pain Points with Shipping Bags and Their Solutions

Shipping Damage

Shipping damage is a top concern for businesses, especially when dealing with fragile items. Poly bubble mailers come with an extra layer of bubble wrap to effectively prevent damage during shipping.

Expensive Shipping Costs

International shipping can be expensive. Poly mailers are lightweight, which helps reduce shipping costs. Their compact size also reduces storage and handling expenses, which helps save on overall costs.

Secure and Tamper-Proof

Plastic mailers come with self-sealing flaps that provide a secure seal to prevent tampering. This ensures that your products reach their destination without any unauthorized access.

Environmental Concerns

Sustainability is becoming increasingly important to both businesses and consumers. Many businesses are concerned about the impact of plastic packaging on the environment. However, modern plastic mailing bags can be eco-friendly. By choosing eco-friendly plastic mailing bags that are recyclable and biodegradable, you can help reduce your carbon footprint while maintaining shipping efficiency.

Customer Experience

A good unboxing experience can significantly increase customer satisfaction. Customizable plastic mailing bags allow businesses to showcase their brand and create a memorable unboxing experience that can increase customer loyalty.

Best Practices for Using Plastic Mailing Bags

Choosing the Right Size

Choosing the right size is essential to protecting your items and reducing shipping costs. Make sure the mailing bag is large enough to accommodate the product without excessive movement, but not so large that it unnecessarily increases shipping costs.

Consider Product Type

For fragile items, choose polyethylene bubble mailing bags, which provide extra protection. For less fragile items such as clothing, standard plastic mailing bags are usually sufficient.

Ensure a secure closure

A secure closure is essential to prevent the mailing bag from opening during shipping. Look for mailing bags with self-sealing tape to ensure a tight seal.

Clear Labeling

Proper labeling is essential to avoid delays or misdirections. Make sure all mailing bags are clearly labeled with the necessary shipping information.

Test Packaging Solutions

Before deciding on a specific type of plastic mailing bag, test it to ensure it meets your shipping needs. This can help identify potential issues and proactively address them.

Why Use Plastic Mailing Bags?

Durability and Protection

Plastic mailing bags are made from durable, high-quality polyethylene that resists punctures, tears, and moisture. This ensures your products remain intact during shipping. Some plastic mailing bags, like plastic bubble mailers, come with an extra layer of bubble wrap for extra cushioning, making them suitable for more delicate items.

Lightweight and Cost-Effective

One of the great benefits of plastic mailing bags is their light weight. They weigh less and take up less space than traditional cartons. This means significant savings in shipping costs, as carriers typically charge based on weight and size. Plastic mailing bags are ideal for items like clothing, books, and other non-fragile items. Poly mailers are compact and can reduce storage and handling costs.


Poly mailers come in a variety of sizes and styles, including poly foam mailers for added protection. This versatility makes them suitable for shipping a wide range of products, from clothing and accessories to electronics and books.

Eco-friendly options

With increasing environmental awareness, many poly mailers are now made with eco-friendly materials, such as recyclable or biodegradable plastics. This allows businesses to reduce their impact on the environment while still enjoying the durability and protection of poly mailers.

Branding opportunities

Custom branded poly mailers can strengthen your brand image and make your packages stand out. Consistent use of your logo and brand colors on shipping materials can attract customers' attention, inspire recognition, and make the unboxing experience more exciting.

What are the types of plastic mailers?

Standard plastic mailers

Poly Bubble Mailers

Poly bubble mailers are an excellent choice for items that need extra protection. These mailers have a layer of bubble wrap inside that provides extra cushioning to protect fragile items during shipping.

Colored Poly Mailers

Colored poly mailers not only add style to your shipments, but they also increase brand awareness. They are available in a variety of colors and can be customized with your brand logo and design.

See-Through Poly Mailers

How to Choose the Right Poly Mailer Size?

Measure Your Product

Make sure the poly mailer is slightly larger than your product to allow for easier insertion and sealing.

Consider Thickness

Thicker mailers offer more protection but may add weight. Choose a thickness that balances protection and cost.

Use a Sizing Guide

Many suppliers offer sizing guides to help you choose the right mailing bag for your product.
