Quality control

QC runs across the production line, not just at the end:

Key inspection results are documented and traceable by production lot — useful for buyers shipping into regulated markets (EU, U.S., APAC).

Materials & sustainability

Standard production uses food-grade virgin (non-recycled) resin for all cosmetic-contact bottles — no recycled content is used without explicit customer approval. For brands with sustainability goals, PCR (post-consumer recycled) PET is offered as an optional drop-in that keeps the same clarity and barrier.

OEM & custom tooling

Beyond the 600+ standard molds, ShiJin Package supports custom bottle development:

Frequently asked questions

What is your production capacity and MOQ?
Our plant runs ~500,000 bottles per day across PET, HDPE and PETG, from a library of 600+ molds. Standard MOQ is 5,000 units per item, with low-MOQ customization programs available for color, print and spray finishing.
Which certifications do you hold?
ShiJin Package is ISO 9001 certified and produces food-grade bottles tested to FDA (21 CFR) and EU 10/2011 food-contact standards, with SGS third-party testing. Certificates are available on request for buyer verification.
Do you use recycled or non-food-grade resin?
Standard production uses food-grade virgin (non-recycled) resin for all cosmetic-contact bottles. PCR (post-consumer recycled) PET is offered as an optional drop-in for brands with sustainability goals; recycled content is never used without explicit customer approval.
How do you control quality?
QC covers incoming resin, in-process dimensions/weight and finish, leak and drop testing on finished bottles, and pre-shipment inspection. Key steps are documented and tied to batch/lot traceability for export orders.
Can you do OEM / custom tooling?
Yes. We support OEM and custom bottle development — new mold creation, custom colors, silk-screen/label/hot-stamp decoration and spray coating — from a 5,000-unit MOQ, with engineering support from sampling to mass production.
