This 4-slot PETG peptide packaging box is a custom 4-vial protective storage case specially designed for 3ml glass peptide vials, lab biological samples and cosmetic lyophilized powder bottles, perfectly suited for retail sample kits and branded brand packaging. Constructed from premium BPA-free rigid PETG plastic, the box features excellent low-temperature resistance and can be safely placed inside refrigerators for long-term cold storage without brittling or deforming.
Equipped with dual-sided thick shock-absorbent black foam inserts, four precision molded circular cavities firmly clamp each small vial to buffer impact, drops and extrusion, effectively avoiding scratches, collision and breakage during transportation, lab sorting and travel carrying. A sturdy metal screw lock buckle ensures tight sealed closure to block dust, moisture and UV light, protecting the activity of sensitive peptide and reagent ingredients. Five classic matte color options including pink, purple, beige, gray and white are available, with custom color matching services to meet personalized brand tone demands.
Full one-stop OEM & ODM customization is supported: buyers can adjust outer dimensions, modify foam cavity sizes, customize the case body and latch colors, and print exclusive brand logos on the exterior surface. ISO 9001 and REACH SVHC certified, this compact stackable vial storage case is widely applied in laboratory sample organization, beauty salon peptide retail packaging, portable cold preservation and bulk wholesale vial transport protective packaging.
