Contract Filling Services for Personal Care Products
A formula only succeeds once it is filled correctly. Underfilled bottles, shifting labels, or inconsistent fill weights can undo months of formulation work. Ally Labs pairs contract filling services with packaging solutions for personal care and non-color cosmetic brands — filling liquids, creams, and gels built for varying viscosities and container types across a wide range of product types.
- 40+ years of manufacturing experience
- cGMP compliant, FDA-registered facility
- Filling support for varying viscosities and containers
How Contract Filling Works
Contract filling moves a finished, approved formula from bulk production into its final packaging. Ally Labs fills supported liquids, creams, gels, and other viscosities into tubes, bottles, jars, and other compatible formats. Tubes are our largest filling format, supported by bottle and other filling capabilities. Equipment and filling methods are selected based on product viscosity, package format, fill requirements, and production volume. Capping, labeling, and case packing can be coordinated as part of the process.

Our filling equipment includes automatic, semi-automatic, and other production setups suited to different run sizes and product characteristics. This gives our team flexibility to match the line to the project and plan appropriate production support as volumes grow.
Most clients source their own packaging components, and our team can review packaging fit and introduce vendors when helpful. Packaging should be evaluated early enough to confirm compatibility with the product and filling equipment. Ally Labs sources production raw materials directly so incoming materials move through established receiving and quality controls. Retail cartons and cartoning are not currently a standard filling-line capability and should be discussed during project planning.
Formulation, manufacturing, filling, and packaging support are coordinated within our Evanston facility. Keeping development and production functions connected through one team supports communication, traceability, and consistent execution as the project moves into commercial production.
Benefits of Contract Filling Services
Consistent Fill Accuracy
Fill weight and fill volume directly affect product performance and customer trust. Equipment calibrated to your product's specific viscosity and container reduces underfills, overfills, and rework — cutting wasted product and keeping each unit consistent from the first case to the last.
Fewer Production Delays
Keeping formulation and filling coordinated can reduce handoff complexity. Once the formula is approved, required testing is addressed, materials and packaging are confirmed or on-site, and the project is production-ready, typical production lead time is approximately six to eight weeks. Actual timing varies by project and production scheduling.
Packaging Solutions Built Around Your Product
Standard packaging does not fit every formula or every brand. Glass jars, plastic bottles, tubes, and other containers are matched to your product's viscosity, use case, and brand presentation, rather than forced into a single default format.
Support Across a Wide Range of Product Types
From lightweight facial oils to thick body creams, our filling process supports a wide range of liquid products. Equipment and settings are adjusted to match your formula, rather than asking your product to fit a single fixed process.
Reduced Contamination Risk
Closed filling systems and controlled handling limit product exposure during transfer from bulk to container. That matters most for creams, lotions, and gels, where consistency and shelf stability depend on a clean fill.
Our Filling & Packaging Options
The right format depends on your product's viscosity, how customers will use it, and how it needs to look on a shelf.
Tube Filling
Tube filling is our strongest capability and our highest-volume format. Tubes require precise fill weight and a clean seal, since an underfilled tube is immediately visible once squeezed. Tube filling supports gels, creams, and treatment products that depend on a controlled, mess-free dispense.
Best for: Facial cleansers, treatment gels, and other squeeze-tube products.
Learn moreBottle Filling
We run a wide range of bottle lines, which makes bottles our second-largest format. Filling lines handle a range of bottle shapes and neck sizes, pairing capping and pump attachment within the same production run, from shampoo to lotion.
Best for: Shampoos, body washes, and pump or flip-top formats.
Learn moreLiquid Filling
Liquids ranging from thin toners to thick lotions require fill accuracy that adjusts for viscosity. Our liquid filling supports consistent volumes across water-thin and heavier formulas alike, so pumps and pour spouts dispense evenly.
Best for: Serums, toners, cleansers, and other pourable or pump-dispensed formulas.
Learn moreJar Filling
Glass and plastic jars call for a different fill approach than bottles, especially for thicker creams and oils that need to settle evenly before the lid is applied. Fill-weight accuracy matters here as much as appearance.
Best for: Creams, masks, and other heavier formulas suited to jar packaging.
Learn moreWho Needs Contract Filling Services
Not every brand needs an outside filling partner. Personal care companies at different stages need different levels of support — here is how to know if contract filling fits yours.
Launching a New Product
Brands moving from concept to first production run often lack in-house filling equipment. Contract filling handles the transition from bulk formula to finished, shelf-ready product without a major equipment investment.
Scaling Past In-House Capacity
Growing order volume can outpace what an in-house line or a small operations team can fill accurately and on schedule. Contract filling adds capacity without adding equipment, staff, or floor space.
Switching Container Formats
Moving from bottles to jars, or adding a tube line, often requires equipment your current setup was not built for. Contract filling lets you change formats without buying new machinery.
Managing Varying Viscosities
Product lines that span thin liquids, thick creams, and gels often need more than one type of filling equipment to fill each accurately — supported across multiple formats at once.

Talk to our teamHow much do contract filling services cost?
Contract filling pricing is scoped project by project based on product viscosity, container type, fill volume, equipment requirements, labeling or packing needs, and order volume. Our team reviews the product and packaging requirements before providing a project-specific quote.
Why do brands use contract filling services?
Contract filling gives brands access to established filling equipment, production expertise, quality systems, and scalable capacity without building and maintaining their own filling operation. Ally Labs evaluates the product, packaging format, viscosity, fill requirements, and production volume to determine the appropriate equipment and line setup.
How are fill weights or volumes controlled during a production run?
Filling equipment is set up around the product, container, and target fill specification, with applicable in-process checks performed during the run. Fill weights or volumes are monitored against established requirements, and adjustments are made when needed as part of the production and quality process.
Can Ally Labs fill different container types?
Yes. Ally Labs supports tubes, bottles, jars, and other compatible packaging formats depending on the product and project requirements. Container dimensions, closures, openings, labeling needs, product viscosity, and filling equipment all affect line fit, so packaging is reviewed before production. Retail cartoning is not a standard filling-line capability and should be discussed during project planning.
Who sources the packaging and the raw materials?
Ally Labs sources the raw materials used in production through our approved sourcing and receiving process. Most clients source their own packaging components, which is our preferred approach, while our team can review packaging fit and introduce vendors when helpful. Proprietary blended fragrance may be client-supplied when applicable to the project.
What product types can Ally Labs fill?
Ally Labs fills supported liquids, lotions, creams, gels, serums, and other approved formats across personal care, non-color cosmetics, household, pet care, and select specialty projects. Filling fit depends on viscosity, formula characteristics, packaging, container geometry, closure requirements, fill volume, and available equipment.
What quality controls apply during contract filling?
Filling at Ally Labs operates within our documented quality system using cGMP-compliant procedures. Depending on the product and project, controls may include equipment cleaning and line clearance, batch and lot traceability, in-process checks, fill verification, labeling review, testing, and finished-product quality review before release.
