Aseptic Carton is one of the most mainstream formats for ambient-temperature packaging of liquid foods, widely used for products such as milk, juice, dairy beverages, and tea drinks. Whether your product uses the Brik (brick-shape), Slim (slender-shape), Prisma (prism-shape), Rex, or Gemina aseptic carton packaging format, we can provide matching roll-fed aseptic packaging materials and configure the corresponding cap specification based on the packaging format (such as formats that support a screw cap). There's no need to work with multiple suppliers separately — packaging materials and caps can be matched and sampled together in one stop, helping shorten your packaging solution finalization timeline. Below are the five packaging formats we currently focus on supporting, along with our corresponding supply capabilities. You can simply let us know the format and volume you need, and we will confirm compatibility and respond with a quotation within 24 hours.

READ MORELile (Taizhou) Technology Co., Ltd is a cap manufacturer, and our starting point for aseptic carton packaging is the same as everywhere else in our range: we already supply caps configured to work across the mainstream aseptic carton formats, including Brik, Slim, Prisma, Rex, and Gemina. Because that cap compatibility work is already done, we are able to extend into supplying matching roll-fed aseptic packaging materials for these same formats, so a customer sourcing caps from us does not have to bring in a second supplier just to get the packaging material side confirmed.
Each carton format tends to suit a different product positioning and filling setup, and the cap specification that goes with it follows from that format rather than being chosen independently.
Brik
The most common brick-shape format for ambient milk and juice, typically paired with 28mm or 30mm screw caps depending on volume.
Slim
A slender retail shape for RTD juice, tea, and RTD coffee, generally configured with a 28mm cap for shelf-facing single-serve packs.
Prisma
A prism shape built for large-volume, family-size milk and juice packs, typically matched to a 30mm cap for wider pour and refill convenience.
Rex
A format chosen for stronger shelf presence and multi-color printing, with cap spec confirmed against the customer's Rex filling equipment.
Gemina
A format suited to mid-to-premium juice, dairy, and functional beverages, with cap configuration confirmed against filling equipment specs.
| Format | Typical Volume Range | Cap Compatibility | Customizable Items |
| Brik | Small to standard-pack, confirmed by equipment | 28mm / 30mm options | Printed graphics, brand logo, cap color |
| Slim | Retail single-serve range, confirmed by equipment | 28mm option | Printed graphics, brand logo |
| Prisma | Large-volume, family-size range | 30mm option | Printed graphics, material strength solution |
| Rex | Wide range, confirmed by equipment | Confirmed by filling equipment | Multi-color printing, brand graphics |
| Gemina | Wide range, confirmed by equipment | Confirmed by filling equipment | Printing process, color scheme |
Exact volume figures and cap dimensions are always confirmed against the customer's specific filling equipment model rather than assumed from the format name alone.
A carton format determines the spout structure and available opening area, and that in turn determines which cap specifications will actually thread and seal correctly. This is why our cap sourcing conversation with a customer usually starts with the carton format and existing filling equipment, not with a cap size picked in isolation. Once the format and volume are known, we can confirm which cap specification fits, and from there decide whether the roll-fed packaging material should be sourced alongside it or handled by the customer's existing supplier.

3
A supply chain system verified by independent third-party certification, with urgent orders prioritized to reduce disruption risk.
Can we buy caps from you without also ordering packaging materials?
Yes, caps remain our core product and can be sourced on their own. The packaging material supply is available as an added option if you want to consolidate suppliers.
How do we know which carton format is right for our product?
This usually depends on your target volume, brand positioning, and existing or planned filling equipment. Sharing those details lets us recommend the closest fit among the five formats.
Do you need our filling equipment model to quote a cap or packaging solution?
Yes, the equipment brand and model determine what will actually run compatibly on your line, so this is one of the first things we confirm.
How long does sample verification take?
Sample production and verification, covering material barrier performance, filling compatibility, and printing effect, is typically completed within 72 hours of the proposal being confirmed.
Can we switch carton formats later without starting over?
Yes, format or volume changes can generally be handled through the same supply chain relationship rather than requiring a completely new sourcing process.
Which cap size works with which carton format?
This varies by format and equipment, Brik commonly pairs with 28mm or 30mm caps, Slim with 28mm, and Prisma with 30mm, while Rex and Gemina are confirmed against your specific filling equipment.
Is there a minimum order quantity?
MOQ depends on the format, volume, printing, and cap customization requested, so it is confirmed once those details are set.
Can printing and branding be customized on both the cap and the carton material?
Yes, cap color and logo can be customized alongside carton printing and graphics, and both are typically confirmed together during the sampling stage.
