Plastic bags are lightweight and flexible
Plastic bags are a popular choice for shipping as they are lightweight and flexible. They are made from a type of plastic called polyethylene, which is a versatile polymer widely used due to its durability, flexibility, and transparency. Polyethylene is also resistant to moisture, chemicals, and UV light, making it suitable for shipping various products.
The lightweight nature of plastic bags helps reduce shipping costs, especially when compared to heavier packaging materials such as cardboard boxes. By using plastic bags, businesses can save on shipping costs and pass those savings on to their customers. Additionally, plastic bags are thin and do not take up much space during transit, allowing for more efficient utilization of storage space.
The flexibility of plastic bags, or poly mailers, allows them to conform to the shape of the items being shipped. This adaptability ensures that the bags can accommodate a wide range of products of different sizes and dimensions. Plastic bags are available in various sizes, from small bags for shipping lightweight items to extra-long mailer bags for long and narrow products like wallpaper or fabric rolls.
The flexibility of plastic bags also extends to their customizability. Businesses can customize the size and thickness of the bags to match the specific requirements of their products, enhancing protection during shipping. Customized plastic bags can also feature unique branding and logos, boosting brand awareness and helping to build a loyal customer base.
Overall, the lightweight and flexible nature of plastic bags makes them a cost-effective, versatile, and protective option for shipping a wide range of items.

They are durable and weatherproof
Plastic bags are a good option for shipping because they are durable and weatherproof. They are commonly used to ship items that are already packaged or delicate and need protection from the elements. Plastic shipping bags are typically made from polyethylene, a lightweight yet strong and durable material. This makes them ideal for shipping as they are flexible and provide a lot of protection for products.
Heavy-duty plastic bags can be used to ship larger items and are especially useful for transporting heavy items such as books or electronic devices. They can also be used to package chemicals such as fertilisers, resins, sand, oil dry, ice melt, pool salt, solar salt, and other minerals. These bags are designed to withstand extreme weather conditions and prevent goods from getting damaged by rain or snow. They are also opaque, which provides confidentiality and security for valuable products.
Poly mailers, a type of plastic bag, are commonly used for shipping apparel or fabric. They are lightweight and sturdy, with a self-sealing fold-over lip, and can be customised with branding and logos. Poly mailers are also available with bubble wrap interiors, providing extra protection for items that are not at risk of being crushed during transit.
Plastic bags are also a cost-effective alternative to cardboard boxes, especially for shipping small, lightweight, and non-fragile items. They are also chemically resistant and have higher tensile strength, ensuring that they do not get punctured easily and that the contents remain dry and protected.

Plastic bags are cost-effective
Plastic bags are a cost-effective option for shipping items. Poly bags are lightweight, flexible, and sturdy, making them ideal for shipping small, soft, and non-fragile items. Their lightweight nature helps reduce shipping costs, especially when compared to cardboard boxes. Poly bags are often custom-sized to match the dimensions of the product, optimizing packaging and shipping expenses. This also ensures that the product doesn't move around during transit, reducing the risk of damage.
The flexibility of poly bags allows them to handle objects of various shapes and sizes. They can be flat or gusseted (with a flat bottom), and some have self-adhesive strips for easy sealing. The thin layer of plastic used in poly bags is tear-resistant and puncture-resistant, providing excellent protection for items during transit. This protective quality of poly bags helps businesses ensure that their products remain safe and secure, reducing customer complaints and refund requests.
Poly bags are also waterproof, protecting items from moisture and external elements. This feature is particularly beneficial for items sensitive to water damage. Additionally, poly bags can be opaque, ensuring confidential or valuable items are kept discreetly out of sight.
For businesses, especially small businesses, poly bags offer a cost-effective solution for shipping. They are inexpensive to purchase, and their lightweight nature helps keep shipping costs low. The ability to customize poly bags with branding and logos further enhances their cost-effectiveness, as businesses can boost brand awareness and reach a wider audience without incurring additional packaging costs.
Overall, plastic bags are a cost-effective option for shipping due to their lightweight nature, flexibility, durability, and ability to provide optimal protection for shipped items.

They are customisable and good for branding
Plastic bags are a popular choice for shipping small, lightweight items. They are lightweight and provide good protection for the contents during shipping. They are also inexpensive, flexible, and sturdy enough to handle objects of all shapes and sizes.
One of the biggest advantages of using plastic bags for shipping is that they can be customised to meet specific sizing requirements. This ensures that products are shipped safely and securely, reducing the risk of damage during transit. Custom-sized bags can also help create a positive impression on customers, making them feel like they are purchasing a high-quality item.
Customisation doesn't just refer to the size of the bag. Businesses can also get their unique branding and logo printed onto the front of their shipping bags, boosting brand awareness and helping to expand their reach. The more people see a company's branding, the more likely they are to remember the company and its products or services. In addition to branding, companies can print any necessary safety instructions or warnings onto the packaging, especially if the contents are potentially dangerous.
The customisability of plastic shipping bags is a significant advantage for businesses, helping to enhance their brand image and improve the customer experience.

Plastic bags are not suitable for fragile items
Plastic bags, or poly mailers, are a popular choice for shipping in the e-commerce industry. They are lightweight, sturdy, and affordable, making them a good alternative to standard packaging. However, they are not suitable for shipping fragile items.
Poly mailers are designed for shipping light and less fragile items. They are thin yet durable, and their self-sealing foldover lip means no tape is needed. They help reduce packaging and shipping costs and are space-efficient during transit. While poly mailers are a good option for items that cannot be crushed, such as apparel or fabric, they are not ideal for fragile items that require extra protection.
Some poly bags are padded with bubble wrap to provide additional protection. Bubble wrap is a transparent packaging material with air pockets that absorb impact and protect items from damage during shipping. However, even with this extra padding, poly bags may not provide sufficient protection for fragile items.
When shipping fragile items, it is crucial to select the right packaging to ensure they arrive intact. Cardboard boxes or specialised shipping boxes with padding or bubble wrap are often better suited for fragile items as they provide more protection during transit. Additionally, selecting the right size of the package is essential to minimise movement and prevent damage.
While plastic bags can be used as a supplementary form of packaging, such as filling empty spaces in boxes to prevent items from shifting, they should not be the primary packaging for fragile items. Choosing the appropriate packaging for fragile items will help ensure their safety and reduce the risk of damage during shipping.
