Carton Boxes in Singapore (2026): Types, Sizes and Where to Buy in Bulk

Key Takeaways

• Carton boxes in Singapore are available in distinct types based on wall construction, shape and intended use. The wrong box type leads to damaged goods, excessive shipping costs or poor storage efficiency.
• Single-wall corrugated boxes cover most standard shipping and storage applications. Double-wall boxes are needed for heavy items (above 10 kg) or high-value goods that need extra crush resistance.
• The four highest-volume carton box keywords in Singapore each have 1,600 monthly searches: carton box, cardboard box, carton boxes and packing boxes. Most buyers search with these general terms, so a clear type guide helps them make a faster decision.
• MillionParcel carries a wide range of carton box sizes in Singapore with no minimum order and island-wide delivery in 3 to 5 working days.

 

Carton boxes are one of the most searched packaging products in Singapore, with over 6,400 combined monthly searches across the top four keyword variants. Yet many buyers do not know exactly which box type they need until they get the wrong one and the product arrives damaged or the box collapses under weight. It is a frustrating and avoidable lesson. This guide helps you get it right the first time.

This guide covers the most useful carton box types available in Singapore in 2026, from standard RSC shipping boxes and double-wall heavy-duty boxes to specialised moving boxes, archive and kraft gift boxes. Each entry covers key specifications, best use cases and where to source them locally in Singapore.

 

How Should You Compare Carton Boxes in Singapore?

Compare carton boxes on three key factors: (1) wall construction (single-wall for standard loads up to 15 kg, double-wall for heavy or high-value items above 10 kg), (2) internal dimensions relative to your product size, and (3) flute type (B-flute for a compact crush-resistant box, C-flute for standard stacking strength, E-flute for a slim presentation box).

Here is how the 10 most common carton box types in Singapore compare.

 

#1. Regular Slotted Container (RSC)

The Regular Slotted Container (RSC) is the most common carton box type in Singapore and globally. All four flaps on both the top and base meet at the centre when folded, making it a simple, flat-pack box that is quick to assemble with packing tape. RSC boxes are available in a wide range of sizes from small (10x10x10 cm) to large (60x40x40 cm) and are the default choice for e-commerce shipping, product storage and general commercial dispatch.

 

#2. Double-Wall Heavy Duty Box

Double-wall carton boxes have two layers of corrugated fluting between three liner sheets, giving them significantly higher stacking strength and crush resistance compared to single-wall boxes. They are the right choice for heavy items (above 10 kg), fragile goods that need extra sidewall protection, export shipments that go through multiple handling points, and any product that will be stacked high in a warehouse. The extra material adds cost and weight per box, so double-wall is not needed for standard e-commerce orders.

 

#3. Courier Shipping Box

Courier shipping boxes are pre-scored RSC-style boxes designed for frequent e-commerce dispatch. They often include hand-cut holes in the side panels for easy carrying and come in sizes optimised for standard courier rate categories (e.g., 30x25x10 cm for small parcels, 40x35x20 cm for medium parcels). Some courier box designs also include a self-locking base that assembles without tape, speeding up the packing process for high-volume operations.

 

#4. Self-Locking / Mailer Box

Self-locking mailer boxes are corrugated boxes designed to lock together without tape. They fold flat for storage and pop up quickly for packing, making them faster to assemble than tape-sealed RSC boxes. They are widely used for e-commerce gifting, cosmetics, subscription boxes and premium product packaging in Singapore. The clean, tapeless exterior gives a more polished presentation than a standard RSC sealed with clear packing tape.

 

#5. Archive / Storage Box

Archive and storage boxes are lidded single-wall carton boxes designed for document and item storage in Singapore offices, warehouses and homes. They typically include a separate flat lid, a label area on the front and side panels, and a base reinforced for stacking. Archive boxes are standardised for A4 document filing and come in depths from 15 cm to 30 cm. They are used by legal firms, accounting practices, medical clinics and any organisation with document retention requirements. For labelling and organising your archive boxes, MillionParcel's sticker label collection includes pre-printed and custom label options.

 

#6. Moving / Relocation Box

Moving boxes are large-format carton boxes designed for house and office relocation in Singapore. They are available in small, medium, large and extra-large formats, and some include built-in rope handles for easier carrying. MillionParcel has a dedicated moving packaging collection with bundles and complementary supplies. For heavy items like books, always use a smaller box to keep the total packed weight manageable.

 

#7. Flat-Pack Die-Cut Box

Flat-pack die-cut boxes are custom-creased carton boxes designed to fold into a shallow, low-profile box form. They are used for clothing, fabrics, stationery, art prints, maps and any product that needs a slim, flat box with a neat finish. Die-cut boxes often have a tuck-front closure and do not require tape, giving them a retail-ready presentation. They are commonly used by Singapore fashion brands, print shops and gift businesses.

 

#8. Wine and Bottle Box

Wine and bottle boxes are carton boxes designed with internal cardboard dividers (partitions) that hold individual bottles upright and prevent them from knocking against each other during transit. In Singapore, they are used by wine importers, craft beverage companies, sauce and condiment producers and artisan food businesses. They are available in configurations from single-bottle to 12-bottle formats and can be sized for standard 750 ml wine bottles or customised for other bottle dimensions.

 

#9. Kraft Paper Box (Gift Box Style)

Kraft paper boxes for gifting are made from natural brown kraft board rather than the grey inner fluting of standard corrugated boxes. They have a smooth, warm natural finish and are used for premium food gifting, bakery packaging, hamper boxes and eco-conscious retail packaging in Singapore. They are thicker and more rigid than regular paper bags but lighter than standard corrugated boxes, sitting between the two in terms of protection and presentation.

 

#10. Custom-Sized Carton Box

Custom-sized carton boxes are manufactured to exact internal dimensions specified by the buyer. They are used when standard-sized RSC or die-cut boxes do not fit the product closely enough, leading to excess void fill, higher shipping volumetric weight costs or product movement during transit. Custom boxes require a minimum order quantity (typically 100 to 500 units for plain custom and higher for printed custom) and a longer lead time than ready-stock boxes.

 

How to Choose the Right Carton Box for Your Business in Singapore?

Choose your carton box based on three things: (1) the weight of the product, (2) the internal dimensions needed, and (3) how many handling points the box will go through before reaching its destination. For standard e-commerce shipping in Singapore, a single-wall RSC or self-locking mailer box is sufficient. For heavy, fragile or export goods, a double-wall box is the safer choice.

• Shipping standard products (clothing, books, accessories, cosmetics) by local courier? A single-wall RSC in the right size is the most cost-effective choice.
• Shipping heavy items (tools, electronics, appliances, furniture parts)? Use a double-wall box and keep the packed weight below the box's rated limit.
• Want no-tape assembly for a cleaner look or faster packing? A self-locking mailer box assembles without tape and looks neater on arrival.
• Moving house or office in Singapore? Buy a set of medium and large moving boxes. Keep books in the small box to avoid overloading.
• Need a specific size that standard boxes do not cover? Request a custom box quote from MillionParcel with your internal dimensions.
