Protective Packaging Collections

Protecting products in transit starts with the right mailing bag. MPS supplies durable, lightweight mailing bags designed to keep orders secure during shipping, with options to suit ecommerce, retail, warehouse and dispatch operations across Australia.

What Are Protective Mailing Bags?

Protective mailing bags are lightweight, flexible packaging designed to protect products during shipping while keeping parcels compact and easy to handle. Unlike cardboard boxes, mailing bags take up less storage space, add minimal weight to shipments and can help reduce postage costs. Many styles also feature a self-seal adhesive strip, making them quick and efficient to pack.

Protective mailing bags are available in a range of materials, including:

  • Polyethylene
  • Kraft paper
  • Bubble-lined materials
  • Padded paper
  • Reinforced plastic
  • Recycled materials.

The right material depends on the product being shipped and the level of protection required.

Where to Use Mailing Bags?

Mailing bags are commonly used for:

  • Clothing and footwear
  • Fashion accessories
  • Documents and printed materials
  • Books and stationery
  • Small electronics
  • Cosmetics
  • Spare parts
  • Soft goods.

Some products can be placed directly into the mailing bag. However, fragile or sensitive items usually require additional protective packaging inside the mailer.

What Are the Benefits of Using Protective Mailing Bags?

Protective mailing bags can help businesses pack orders quickly while reducing unnecessary packaging weight and storage requirements. Their benefits include:

  • Lightweight. Mailing bags are lighter than many cardboard cartons, which can help reduce the overall parcel weight and make orders easier to handle.
  • Easy construction for packaging. Many mailing bags include a peel-and-seal adhesive strip. Warehouse teams can insert the product, remove the backing, and close the bag without using extra sealing equipment.
  • Compact design. Unfilled mailers lie flat and require less storage space than assembled cartons. They are perfect for ecommerce businesses and warehouses with limited packing space.
  • Protection from shipping conditions. Depending on the material, protective shipping bags can help protect products from dust, dirt, moisture, and scratches. The exact level of protection depends on the bag construction and the product packed inside.
  • Suitable for many products. Mailing bags for ecommerce are available in various sizes, materials, and levels of protection. They can be used for soft items, documents, accessories, small products, and selected fragile goods.
  • Cost-effective packaging. Mailing bags use less material and take less time to pack than larger packaging formats. Choosing the right size also helps minimise unused space inside each parcel. 

The Range of Protective Mailing Bags at MPS

MPS offers protective mailing bags for a wide range of ecommerce, warehouse, and retail shipping requirements.

Padded mailing bags

Padded mailing bags include an inner cushioning layer that helps protect products from impact, vibration, and surface damage.

They are used for:

  • Jewellery
  • Books
  • Cosmetics
  • Electronics
  • Accessories
  • Delicate retail products.

Padded mailers provide more protection than an unlined satchel but remain lighter and more compact than boxes.

Bubble mailing bags

Bubble mailing bags contain a bubble-lined interior that cushions products during handling and transport.

They are suitable for products that need protection from minor impacts, vibration, scratches, or movement during delivery.

Bubble mailers can be useful for small electronics, media products, parts, and other items that do not require a full cardboard carton.

Poly mailing satchels

Poly mailing satchels are lightweight, flexible, and moisture-resistant. They are used for clothing, textiles, and other soft, non-fragile products.

Poly bags are practical for high-volume ecommerce fulfilment because they are quick to pack, easy to store, and available in multiple sizes.

Heavy-duty mailing bags

Heavy-duty mailing bags are made for products that require greater resistance to tearing, puncturing, or rough handling.

They may be suitable for:

  • Industrial components
  • Bulky products
  • Heavy textiles
  • Equipment parts
  • Items with irregular edges
  • Long shipping journeys.

For demanding applications, heavy-duty poly bags can provide more protection than standard lightweight mailing satchels.

Paper mailing bags

Paper mailers can be used to ship documents, books, printed products, and some retail items. Some options include padding or reinforced construction for additional protection.

Check the product specifications to confirm whether a paper mailer is suitable for the expected shipping conditions.

Mailing bags with adhesive seals

Self-sealing mailing bags contain an adhesive strip that securely seals the opening.

These bags help speed up packing, reduce tape use, and create a clean parcel presentation. They keep products securely enclosed during transit.

Some mailing bags include a second adhesive strip for returns.

How to Choose the Right Protective Mailing Bag?

The correct mailing bag should fit the product securely and provide enough protection for the shipping journey. To find the right option, follow these steps:

1. Measure the product

Measure the item's length, width, and thickness, then compare them to the bag dimensions. Always confirm whether the listed measurements include the flap. The usable internal size may be smaller than the full external dimensions.

2. Consider the product shape

Soft, flexible products can fit in a close-fitting poly satchel, while rigid or irregular products need more space to fit without placing excessive pressure on the seams. Sharp corners may also require a stronger or thicker bag.

3. Choose the required protection level

Consider how easily the product could be damaged.

Use a basic poly mailer for:

  • Clothing
  • Fabric products
  • Soft accessories
  • Items already packed in retail packaging.

Use a padded or bubble-lined mailer for:

  • Small electronics
  • Jewellery
  • Books
  • Cosmetics
  • Sensitive components
  • Products that may scratch or break.

Products that require additional protection may need bubble wrap before being placed in the mailing bag.

4. Check the packed weight

Don’t overload mailing bags. A heavy product can stretch the material and weaken or tear the seams.

Check the bag specifications and consider a reinforced or heavy-duty option for denser products.

5. Assess moisture exposure

Poly mailers provide useful moisture resistance during normal shipping. However, they are not fully waterproof under all conditions.

Products that are sensitive to moisture may need an additional sealed inner layer.

6. Consider the shipping journey

You'll need a strong mailing bag when:

  • The parcel will travel a long distance.
  • The item will pass through several freight depots.
  • The product has sharp or irregular edges.
  • The shipment may face rough handling.
  • The contents are valuable or sensitive.

7. Don’t overlook presentation

The appearance of the parcel can influence the customer experience.

Choose a mailing bag that:

  • Fits neatly around the product.
  • Does not appear overfilled.
  • Provides a clean sealing area.
  • Has enough room for labels.
  • Matches the product and brand presentation.

For easy shipping

Stock Cardboard boxes


Stock cardboard boxes are one of the most dependable packaging options for everyday dispatch, storage and transport. MPS Packaging Australia carries a wide range of ready-made carton sizes, making it easy to select a box that suits your product without waiting on custom manufacturing. Our cartons are made from durable corrugated cardboard, offering strength, stackability and reliable protection during freight. They arrive flat packed to save space and can be quickly assembled when needed, ideal for warehouses, online retailers and fulfilment centres. Whether you need small postal cartons or large bulk boxes, our stock range provides a simple and economical solution for clean, professional packaging.

Protecting your pallet corners

Cardboard corners


Corner boards, also known as edge protectors, are an essential packaging accessory used to reinforce and stabilise loads during transit. By placing them on the edges of your pallet, they distribute strapping and stretch wrap pressure evenly to prevent crushing, tearing or product damage. MPS Packaging Australia supplies both kraft and moisture-resistant corner boards in a range of lengths and thicknesses, making them suitable for everything from light retail goods to heavy industrial products. They help keep pallet loads square, improve stacking strength and present a more professional finish — ideal for shipping companies, warehouses and manufacturers who demand consistency and load stability.

Cardboard Angleboard

Strap guards

Strapping Corner protectors

Strapping protectors are a simple but important accessory used to prevent damage where the strap contacts the edge of your product. By spreading the pressure of the strap, they stop corner dents, cuts and abrasion during tensioning and transport. MPS Packaging Australia supplies both plastic and cardboard protectors for use with PET and steel strapping, helping you secure loads safely without marking the product. They’re lightweight, easy to apply and a cost-effective way to improve presentation and load stability.

Strapping protectors

Air pillow cushioning and Void fill

Air pillows

Air pillows are one of the most efficient ways to fill voids and protect goods inside cartons. They provide lightweight cushioning that prevents movement and absorbs impact during freight, without adding unnecessary weight like traditional void fill. MPS Packaging Australia supplies both pre-filled air pillows and on-demand air pillow machines that create protective cushions as you need them. With fast output speeds and compact film rolls, these machines are ideal for dispatch areas with limited space and high packing volume. Air pillows offer clean, dust-free packaging, reduce material waste and present a professional finish for e-commerce, warehouses and fulfilment centres.

Air pillows

a classic solution to protection

Bubblewrap

Bubble wrap remains one of the most trusted protective packaging materials for cushioning and wrapping goods of all shapes and sizes. The air-filled bubbles absorb impact and prevent scratches, dents or breakages during transit, making it ideal for fragile items, electronics, glassware and components. At MPS Packaging Australia, we supply bubble wrap in multiple grades, widths and roll lengths, including heavy-duty and anti-static options for sensitive products. It’s easy to cut, lightweight, and provides reliable surface protection while keeping freight costs low. Whether you’re packing single parcels or high volumes in a warehouse, bubble wrap offers dependable and versatile protection every time.

Made from degradable corn starch

Biofill Void fill


Biofill is an eco-friendly alternative to traditional foam void fill, designed to protect products during shipping while reducing environmental impact. Made from biodegradable plant-based materials, biofill cushions goods inside cartons and fills voids to stop movement in transit. It provides excellent shock absorption, is lightweight, and can be easily disposed of or composted after use. MPS Packaging Australia supplies biofill as a ready-to-use loose fill option, ideal for e-commerce packaging, fragile goods and fulfilment centres aiming to improve sustainability without compromising protection. It’s a clean, dust-free and environmentally responsible solution for everyday packing.
