Stock Boxes

Stock Boxes for Packaging

Reliable, ready-to-use carton packaging is a core requirement for any Australian business that dispatches, stores, or distributes goods regularly. Premium Packaging’s stock box range covers the most practical and proven corrugated carton format in commercial use, the Regular Slotted Carton (RSC), across a carefully chosen set of sizes and board grades to suit a broad range of business applications.

Whether your operation involves daily eCommerce order fulfilment, high-volume freight dispatch, or organised warehouse storage, having the right stock box available when your team needs it keeps your packing line running without interruption. All boxes are supplied flat in bulk cartons, with volume-pack pricing that scales to match your procurement requirements.

The RSC Format: Why Commercial Buyers Choose It

RSC stands for Regular Slotted Carton. It describes a corrugated box where all four top and base flaps are equal in length and meet at the centre when folded closed. Once secured with packaging tape, the result is a firm, consistent enclosure suited to a wide variety of goods across standard freight and storage conditions.

This format has remained the industry standard in commercial packaging for good reason. RSC boxes are fast to erect, which matters when your team is packing at volume and speed is a genuine operational requirement. Their uniform dimensions make palletising and freight load planning consistent from one order to the next. They stack securely in transit and in warehouse racking. And across all of these functions, they deliver predictable performance, order after order.

Supplied flat, stock boxes take up far less storage space than pre-erected alternatives. This allows businesses to keep adequate carton stock on hand without sacrificing valuable warehouse or dispatch floor space, a practical advantage that compounds quickly when ordering in bulk.

Available Sizes and Board Grades

Premium Packaging stocks RSC cartons across a practical span of dimensions suited to different product types, freight classifications, and storage requirements. All sizes are listed as length x width x height.

A4-footprint cartons (320mm x 220mm base)

Available in five depth options: 110mm, 160mm, 195mm, 230mm, and 280mm. This group covers document packaging, book and paper product distribution, lightweight retail goods, and a wide range of eCommerce applications. Board grades across this group include 4B and 3B corrugated, with specific variants rated for standard ream quantities and a 10kg capacity option.

A3-footprint cartons (440mm x 330mm and 460mm x 330mm base)

Available in two standard depth options of 160mm and 280mm, plus a dedicated Digital Printer Carton variant at 460mm x 330mm x 160mm. These cartons offer greater internal volume for larger products, multi-unit shipments, and outbound goods from manufacturing, wholesale, or distribution operations. All use 4C corrugated board.

All boxes are sold in carton packs of 25 or 30 units, with per-box pricing available for orders of 8 or more packs for businesses procuring at greater volume.

Industries That Rely on Stock Boxes

eCommerce and Online Retail Operators

For businesses processing daily outbound orders, RSC stock boxes form the backbone of an efficient dispatch workflow. Consistent sizing and flat-pack supply allow fulfilment teams to manage packaging stock without cluttering working areas, and the available size range covers most standard product categories without the cost and lead time associated with custom packaging.

Logistics and Distribution Centres

In high-throughput distribution environments, carton uniformity is a genuine operational advantage. RSC boxes palletise evenly, handle reliably in transit, and maintain structural integrity throughout the warehouse-to-recipient supply chain. Their straightforward assembly also reduces handling time in fast-paced pick-and-pack operations.

Manufacturers and Production Facilities

Manufacturers packing outbound goods for retail or wholesale channels need a carton that performs consistently without adding complexity on the production floor. Stock boxes in the correct sizes remove the need for custom solutions on standard product lines, and bulk procurement keeps packaging supply costs predictable and manageable.

Retail and Wholesale Businesses

From bundling multi-unit products to organising back-of-house inventory, RSC stock boxes serve retailers and wholesalers across a wide range of day-to-day tasks. The variety of depth options in the A4 carton group allows different product configurations to be packed neatly without excess internal void.

Print and Document Services

The A4-footprint carton range is specifically suited to businesses working with paper reams, printed materials, books, and documents. The 10 kg-rated variant and the Digital Printer Carton option address the specific weight and dimension requirements of print and document handling operations.

What Sets These Stock Boxes Apart

Multiple size options in a single range

With eight distinct sizes and board-grade combinations available from a single supplier, businesses can select the right carton for each product line without sourcing from multiple suppliers or carrying unnecessary inventory due to incompatible sizes.

Flat-pack supply for space efficiency

Every stock box is supplied flat, so your team can erect each carton as needed rather than store bulky pre-built boxes. This is a straightforward but significant benefit for any business managing limited warehouse or dispatch floor space.

Consistent board grade performance

Cartons within each product code maintain the same corrugated board specification from order to order. Your packing team can rely on the same structural performance and sealing behaviour without having to compensate for batch-to-batch variation.

Bulk carton quantities with volume pricing

Stock boxes are sold in packs of 25 or 30, with per-box pricing decreasing for orders of 8 or more. This pricing structure supports both regular top-up orders and larger procurement runs, giving businesses flexibility around their ordering cadence.

Australia-wide delivery from a trusted supplier

Premium Packaging dispatches to businesses across Australia with reliable lead times. Whether you are based in metro Sydney, regional Victoria, or anywhere in between, we can support your ongoing packaging supply requirements.

A Responsible Packaging Choice

Corrugated cardboard is among the most widely recycled packaging materials in commercial use across Australia. The RSC stock boxes in the Premium Packaging range are manufactured from corrugated board and are fully recyclable at the end of use. For businesses working toward environmental targets, managing packaging waste responsibly, or responding to sustainability expectations from customers and supply chain partners, corrugated cardboard cartons represent a practical and measurable step in the right direction.

Pair Your Stock Boxes with the Right Packaging Supplies

Stock boxes perform best as part of a complete packaging setup. Premium Packaging supplies a full range of complementary products to support your dispatch, warehousing, and distribution workflow, including packaging tape and tape dispensers for fast, consistent carton sealing, bubble wrap for protecting goods within the carton during transit, corrugated cardboard rolls for void fill and internal wrapping, kraft paper rolls for product cushioning and presentation, corner protectors for fragile or high-value goods requiring additional transit protection, and pallet wrap for securing carton loads prior to freight dispatch.

Sourcing all core packaging materials through a single supplier simplifies your procurement, reduces administrative overhead, and helps maintain a consistent supply across your whole operation.

Frequently Asked Questions

What does RSC mean, and why is this box format used so widely in commercial packaging?

RSC stands for Regular Slotted Carton. It refers to a corrugated box design in which all four flaps at the top and base are the same length and close flush at the centre. This format is the most common corrugated box type used in Australian commercial operations because it assembles quickly, maintains consistent dimensions for palletising, and delivers reliable structural performance under standard freight and storage conditions.

What are the differences between the 3B, 4B, and 4C board grades in the stock box range?

The board grade refers to the weight and flute profile of the corrugated material used in construction. The A4-footprint cartons are available in 4B and 3B grades, while the larger A3-footprint cartons use 4C board. Higher board grades generally provide greater stacking strength and resistance to transit pressure, making them appropriate for heavier goods or longer supply chains. If you are unsure which grade suits your product and freight requirements, our team is happy to provide a recommendation.

Are the boxes supplied flat, and how does this benefit my warehouse or dispatch area?

Yes. All Premium Packaging stock boxes are supplied flat in carton packs of 25 or 30 units. Flat supply reduces the storage footprint of your packaging stock considerably compared to pre-erected alternatives, which is a real advantage for businesses managing limited floor space in a warehouse, stockroom, or dispatch area. Cartons are erected by your team as needed during the packing process.

Can I order stock boxes in bulk for an ongoing, regular supply?

Yes. All stock boxes are available in bulk carton packs, with per-box pricing decreasing at 8 packs or more. For businesses with consistent, high-volume packaging requirements, our team can discuss supply arrangements to ensure your stock levels stay aligned with your dispatch and production cycles throughout the year.

What other packaging products should I use alongside stock boxes to complete a commercial dispatch setup?

For most business dispatch operations, stock boxes work best alongside packaging tape and a tape dispenser for fast carton sealing, bubble wrap or corrugated cardboard rolls for internal product protection, and pallet wrap if cartons are being palletised for freight. Corner protectors are also worth considering for fragile or high-value goods. Premium Packaging stocks all of these products, allowing your business to manage its entire packaging supply through a single account.
