How to Choose Packaging for Sunscreen

Sunscreen is a performance product, and packaging affects performance in two ways: it can interact with the formula, and it influences how much product the user actually applies.

Dose matters for SPF

SPF is measured at roughly 2 mg of product per cm² of skin. Packaging that dispenses a predictable amount helps users get closer to that figure:

• Metered airless pump at 0.30–0.50 ml per stroke — most controllable
• Tube with a defined orifice — good, with a squeeze-and-measure habit
• Free-pour bottle — least controllable, and the reason face SPF often underperforms

Format comparison

Format	Protection	Best for	Notes
Tube with EVOH barrier	High (limited air ingress)	Creams, thick fluids, SPF 30–50+	Wide orifice for viscous formulas, full-surface print
Airless bottle	Highest	SPF serums and fluids, facial SPF	0.30–0.50 ml doses, travel-safe locking
Standard pump bottle	Moderate	Fluid SPF for body	Air enters during dispensing
Fine-mist sprayer	Varies with dose	Non-aerosol sun mists	Requires dose uniformity testing
Tube for body	High	150–300 ml body formats	Best cost per ml for sun care

Compatibility: the sunscreen-specific risk

SPF formulas often contain solvents, emollients and UV filters that interact with plastics and adhesives. Typical problem areas:

• PET with solvent-rich or oil-forward formulas — stress cracking risk
• Label adhesives lifting under oil contact
• Print and coating adhesion degrading with frequent reapplication
• Fragrance loss through flexible walls

Test before production: fill the pack, store 4–12 weeks at 40 °C, then check deformation, weight loss, print adhesion and label edges.

Material selection

• HDPE — the safest general choice for sun care, available with recycled content
• PP — good chemical resistance for fluid and gel SPF
• PE tubes with EVOH barrier — best barrier option for creams
• PET — only with a compatibility test

Capacity guidance

Use	Capacity	Rationale
Facial SPF	30–50 ml	Paired with daily routine use
Daily body SPF	100–200 ml	Two to four weeks of use
Beach / sport	150–300 ml	High-consumption occasions
Travel	50–100 ml	Cabin-compliant, resealable

MOQ: tubes start at 3,000 pcs (5,000 for barrier constructions), airless bottles at 3,000 pcs, and stock bottles at 1,000 pcs. Sampling is 5–20 working days and production 15–30 working days.
