Keyuan Packaging 0.3oz/8ml 29-400 PET Straight Sided Double Wall Jar with Flush ABS Cap and PP Sealing Disc

What this packaging is

Straight-sided and compact, this double-wall PET jar delivers a clean, structured silhouette that punches above its 8ml size. The 0.3oz/8ml 29-400 PET Straight Sided Double Wall Jar pairs a flush ABS cap with a PP sealing disc for a secure, tamper-resistant close that keeps delicate formulas protected. At just 31mm wide and 36mm tall, the format is purpose-built for travel-sized eye creams, lip masks, and lip balms. The 29-400 neck finish ensures broad closure compatibility, and the smooth cylindrical surface accepts silk screen printing, hot stamping, or labeling for clean brand customization.

Why brands choose this

• Travel-ready format meets eye and lip care category norms: At 8ml and 31mm wide, this jar hits the sweet spot for travel-sized and sample-format eye creams, lip masks, and balms — a segment seeing sustained growth as consumers build on-the-go routines and discovery sets continue to drive category trial.
• Double-wall construction elevates perceived product value: The dual-wall design adds structural rigidity and a premium hand-feel that belies the jar's compact size, making it a smart choice for brands that want their entry-level or travel SKUs to feel consistent with full-size product quality on shelf.
• Flush cap and sealing disc deliver confident, leak-safe closure: The flush ABS cap sits flush with the jar's rim for a clean, modern profile, while the PP sealing disc adds a secondary barrier that protects formula integrity during transit — critical for balms, masks, and occlusive eye creams that can shift at temperature.
