Customer Projects
Packaging solutions trusted by global brands
Every project is built on the same manufacturing foundation — in-house tooling, fast sampling and consistent quality. Here are a few examples of what that looks like in practice.
Quick answer: These four projects show the range of work Shijin handles — skincare, personal care, cosmetics and household cleaning — and what stays constant across all of them: in-house tooling, sampling before commitment, controlled decoration and traceable quality. Shijin has manufactured plastic packaging since 2003 from 15,000 m² of production space in Shenzhen, Huizhou and Guangzhou, with 2,000+ molds, 30+ production lines and a capacity of 200,000 pieces per day. Client names are withheld out of respect for confidentiality agreements; the technical approach in each project is described in full below.

Skincare
Luxury Serum Packaging
A premium skincare brand needed lightweight, glass-like packaging for their serum line.
Challenge
Achieve a premium glass-like look with lightweight, shatter-resistant PETG material suitable for e-commerce shipping.
Solution
Custom PETG dropper bottle with frosted finish, private mold with SJ marking, and color-matched dropper assembly.
Personal Care
Sustainable Body Wash Range
An EU personal care brand needed GRS-certified PCR packaging for their new body wash collection.
Challenge
Meet EU packaging regulations with fully documented PCR supply chain and mono-material design for recyclability.
Solution
PCR HDPE bottles with GRS-certified documentation. Mono-material construction. Custom silk-screen decoration with water-based ink.
Cosmetics
Custom Lotion Bottle Line
A US cosmetics brand needed a complete custom bottle line with private molds and full decoration.
Challenge
Develop 4 SKU sizes from 50ml to 500ml with consistent brand identity across all formats.
Solution
Private molds for all 4 bottle sizes. Custom color masterbatch. Silk-screen logo and hot-stamp gold accent on every bottle.
Household
Trigger Spray Cleaning Line
A global household cleaning brand needed HDPE bottles with trigger sprayers for consistent retail packaging.
Challenge
Deliver 500ml and 1000ml HDPE bottles with chemical-resistant trigger sprayers. Consistent quality across large reorder volumes.
Solution
HDPE bottles with calibrated neck finish for trigger compatibility. In-line QC at every stage. Batch traceability for full supply chain visibility.
From first message to shipping carton
Most packaging projects stall for the same reason: the buyer cannot tell what happens next, or when they will be asked to pay. Here is the sequence, so you can plan internally before you commit.
Brief & feasibility
You send capacity, material preference, decoration and target quantity. We come back with what is possible from stock molds, what needs a new mold, and an honest indication of cost and lead time. No obligation at this stage.
Quotation & mold decision
If a private mold is required, we quote the tooling separately from the unit price so you can see exactly what you are paying for. Existing molds from our 2,000+ library avoid that cost entirely — worth checking before you commission anything new.
Sampling & approval
Samples are produced for your sign-off on shape, colour, finish and decoration. Nothing goes into mass production until you have approved a physical sample — this is the single biggest protection against a costly mistake.
Production & inspection
Molding, decoration and assembly run against the approved sample, with IQC, IPQC and OQC gates in between. You can send a third-party inspector or ask for a live video walkthrough during the run.
Packing & delivery
Cartons are counted and marked against the packing list, then shipped EXW, FOB or on your nominated forwarder. Export documents are prepared for your market, and batch records stay on file after delivery.
What every project includes
These are not add-ons or premium tiers. They are part of how we build packaging, whichever project you look at above.
Bottle & closure together
Bottles, caps, pumps, sprayers and droppers sourced and fit-tested as one assembly, so the seal is our responsibility rather than a dispute between two suppliers.
In-house decoration
Silk screen, labelling, hot stamp and spray coating handled in-house — decoration lead times stay inside our control rather than depending on an outside print shop.
Documented quality
Inspection records for every batch, retained samples, and third-party test reports arranged for your destination market when required.
Consistency on reorder
Colour, wall thickness and print position are held to the approved standard sample, which is what makes a fourth reorder match the first.
Where these bottles end up
The same molding and finishing capability serves very different products. If your category is not listed, it is still worth asking — the constraint is usually the material, not our capacity.
Cosmetics & skincare
Serum, lotion, toner and cream bottles in PET, PETG and HDPE, with droppers, lotion pumps and airless options. Premium finishes for shelf presence.
Personal care & hair
Shampoo, conditioner and body wash bottles from travel size to 1,000 ml, with disc-top caps, flip-tops and pumps.
Household & cleaning
HDPE trigger sprayers and detergent bottles built for chemical resistance and repeated handling, at retail-scale volumes.
Automotive & industrial
Car-care, lubricant and chemical bottles where solvent resistance and seal integrity matter more than transparency.
Before you start a project
Often, yes. We hold 2,000+ existing molds, and many projects are built on the closest match plus custom colour, decoration and closure. That removes tooling cost and shortens the timeline considerably. Send us your desired capacity and shape and we will tell you honestly whether an existing mold is a good fit or whether a private mold is the better route.
MOQ depends on the product and the mold. For custom accessories and closures, orders start at 5,000 pcs in white, black or natural, or 10,000 pcs for custom colours. Stock-mold bottles can sometimes be supplied in smaller trial volumes with a start-up fee — ask, and we will tell you what is genuinely possible rather than quoting a blanket rule.
Private tooling is quoted and invoiced separately from the unit price, so you can see what you are paying for and what it buys. Many clients prefer this to a hidden tooling cost buried in the piece price. Where a project is large enough, amortising tooling across the order is a conversation worth having.
Yes. Silk screen, labelling, hot stamp and spray coating are all done in-house, so your artwork is applied under our own QC rather than by an outside printer. Colour is matched against an approved masterbatch sample and a physical standard chip is kept for reorder consistency.
Custom tooling is made for your project and can be marked with your own identification. We do not resell a client's private mold to another customer. If your brand requires it, we will sign your NDA before receiving technical drawings — that is standard practice for us, not an unusual request.
Five things: target capacity, material preference (or the product it will hold), closure type, decoration requirements, and order quantity. Add your destination country and any deadline you are working to, and the quote comes back with the right export documentation rather than needing a second round.
Always. Nothing enters mass production until you have approved a physical sample for shape, colour, finish and print. Stock-mold samples typically ship quickly; custom decoration samples take longer because the print setup has to be mounted. You will be told which applies before you commit.
Shijin packaging ships to buyers in 30+ countries, with strong experience in North America, Europe, Southeast Asia and the Middle East. Export paperwork — certificates, test reports and translations — is prepared in English as standard, since a delayed customs clearance costs far more than the document itself.
