What size box fits 5-pack and 10-pack sheet mask sachets, clay jars and eye patch tubs?

How do I measure a stack of 5 or 10 foil sheet mask sachets without front-panel bowing?

The number-one sizing mistake in sheet mask packaging is measuring one empty flat foil pouch, multiplying its thickness by five or ten, and ordering a carton to that depth. Once a foil sachet is filled with a folded cotton, microfiber, hydrogel or bio-cellulose mask plus 25 ml (0.85 fl oz) of viscous serum, the pouch forms a teardrop profile when standing upright. If the front-to-back carton depth (W) is too tight, the bottom third of the front panel bulges outward like a pillow and pops the bottom tuck flap open. Before requesting a quote for custom printed face mask boxes, stand 5 or 10 filled sachets upright in a row between two flat books on your table, just as they will stand inside the retail box. Measure three numbers: the pouch width from left seal to right seal, the combined front-to-back depth across the thickest lower belly of the standing stack, and the pouch height from bottom seal to top tear-notch edge.

1. Carton Length (L): take your flat sachet width (usually 4.375 to 4.5 in) and add 3/16 to 1/4 inch so the side heat seals never scrape or curl.
2. Carton Width / Depth (W): measure the standing stack of 5 or 10 filled pouches across the bottom serum bulge and add 1/8 inch.
3. Carton Height (H): take your sachet height (usually 6.0 to 6.25 in) and add 1/4 inch so the top tuck flap closes cleanly without folding the top seal.
4. Alternating stack trick: if your serum pouches are extra plump (30 ml+), pack every second pouch upside down or add 3/16 inch extra depth.
5. Single-mask envelopes: for 1-mask retail sleeves or hang-tab folders, allow a 3/8 inch (0.375 in) spine gusset so the envelope lies flat.

What are the typical box dimensions for sheet mask multipacks, clay jars and eye patch tubs?

While CubitPack cuts every order to your exact inside Length × Width × Height with zero die charges, most facial sheet masks, under-eye hydrogel patches, wash-off clay jars and squeeze tubes follow eight standard retail footprints. Use the chart below to benchmark your product line before measuring your physical samples. Notice how sachet cartons keep Length and Height constant (for example 4.75 × 6.5 inches for a standard 4.5 × 6.25 inch pouch) and only scale the front-to-back Width (W) as you move from a single mask envelope (0.375 in) to a 5-pack (1.375 in), a 10-pack dispenser (2.5 in) or a 15-pouch counter display tray (4.25 in).

How do I size boxes for 50 ml and 100 ml clay mask jars and hydrogel eye-patch tubs?

Wash-off kaolin clay masks, charcoal mud treatments, overnight sleeping masks and 60-count under-eye hydrogel patch tubs are packed in wide-mouth glass or thick double-wall acrylic jars. When sizing a square custom auto lock bottom box for a round jar, measure the outside diameter across the widest part of the jar base or cap, then add your insert allowance. If your mask jar is molded from heavy frosted glass, adding an internal E-flute corrugated liner sleeve requires an extra 3/16 inch (0.1875 in) on both Length and Width. On Height, measure from the bottom of the jar to the top of the screw lid, and add 1/4 inch to 3/8 inch of head clearance if you want a die-cut paperboard neck collar with a retaining loop to hold a mini silicone brush, cosmetic scoop or plastic eye-patch tweezers above the cap.

What box dimensions fit under-eye hydrogel blister trays and squeeze-tube masks?

Individual pairs of gold or collagen under-eye hydrogel patches and hydrogel lip masks are usually thermoformed inside rigid plastic blister trays sealed inside a flat foil pouch (typically 4.25 × 5.25 inches). Because the inner plastic tray prevents the liquid from pooling at the bottom, eye-mask pouches stack much flatter than full-face sheet masks: five pairs fit neatly inside a 4.5 × 1.25 × 5.5 inch straight tuck carton or custom drawer box. For peel-off charcoal masks, enzyme gel masks and hydrating sleeping masks packed in 50 ml to 100 ml (1.7 to 3.4 fl oz) squeeze tubes, measure the width of the flattened top crimp seal (which is always wider than the round tube cap) for your carton Length (L), measure the round cap diameter for your carton Width (W), and add 1/8 inch to the total tube height.

How do I size a pop-up counter display (PDQ) box for single sheet masks?

Beauty boutiques, med-spas and apothecaries love selling single sheet masks as impulse add-ons by the register alongside 5-pack boxes on the main shelf. A custom counter display box ships as a closed rectangular carton with a perforated front apron and a scored top lid that folds backward to lock into a vertical billboard header. To hold 15 to 20 standard 4.5 × 6.25 inch sheet mask sachets upright in a single front-facing file, size the display tray interior to 5.0 × 4.5 × 6.75 inches, with the front cut-down lip sitting at 2.25 inches high so the top two-thirds of the front sachet artwork stays completely visible to shoppers. If you want a two-column counter display that holds two different mask formulas side by side (15 hydrating masks on the left and 15 brightening masks on the right), widen the interior tray Length to 9.75 inches and add a central vertical paperboard divider wall.

What are the most common custom face mask box sizing mistakes?

Foil serum pouches, wide-mouth glass jars and mini applicator tools each have a specific clearance rule. Avoid these five sizing errors

1. Measuring the thin top edge of a foil sheet mask sachet instead of the thicker bottom third where 25 ml of liquid serum settles.
2. Making the carton Length equal to the exact flat width of the foil pouch, which bends and crinkles the left and right heat seals when packed.
3. Forgetting to add 1/4 to 3/8 inch of top head clearance above a clay mask jar lid to hold the mini spatula or hydrogel tweezers.
4. Sizing a squeeze-tube mask box to the round cap diameter on both sides while forgetting that the flattened top crimp seal is 1/2 inch wider.
5. Using an unlined single-wall carton for a heavy 100 ml glass clay mask jar without adding 3/16 inch for an internal corrugated collar.
