Capping Machines for Bottles and Jars

Capping Machine Categories
Longteng’s capping machine range is organized into five existing categories: Lug, Press, ROPP, Screw and Trigger Capping Machines. Identify the cap and container first, open the matching category, and compare the available models for your packaging line.

trigger and spray-pump capping machines

How to Choose a Capping Machine
Start with the cap type and material, bottle or jar neck, container shape and required closure method. Also confirm whether caps will be placed manually or supplied automatically, and whether the machine must connect with filling, labeling or other packaging equipment.
Cap Types for Bottle Capping Machines
Screw cappers handle threaded caps; ROPP machines form roll-on pilfer-proof aluminum closures; press machines apply press-on caps; lug cappers close twist-off jar lids; trigger cappers handle trigger or spray-pump closures. Final compatibility must be checked with actual samples.
Capping Machine Applications
The correct machine depends on the actual bottle, jar and cap combination used in food, beverage, cosmetic or daily chemical packaging. Send representative containers and closures so the application can be evaluated against an existing Longteng model.
Technical Parameters to Confirm
Before selection, confirm container dimensions and shape, cap dimensions and material, neck finish, closure method, cap feeding requirement, line layout, power standard and upstream or downstream connections. Any speed, torque, accuracy or capacity value must come from the selected product specification and sample validation.
Cap Feeding Systems
Caps may be placed manually or supplied by an automatic feeding system, depending on the cap and line configuration. Select the feeding solution only after confirming cap geometry, orientation and required line integration. Cap feeding remains a supporting system, not a new capping-machine category.
Capping Machine Projects
Project references should show the real container, cap, machine configuration and line context. Link only to existing Longteng case pages and do not imply that one project specification applies to every capping application.
Capping Machine FAQ
Which capping machine matches my cap type?
Match the closure to one of the five existing categories: screw, ROPP, press, lug or trigger. Final selection requires real cap and container samples.
What samples should I provide before machine selection?
Provide representative bottles or jars, caps, neck details and any relevant line information. Samples allow the existing model and closure method to be checked without assuming compatibility.
Can the capper connect to an existing filling or packaging line?
Integration must be reviewed using the current line layout, conveyor height, control sequence, available space and upstream or downstream equipment. No connection should be promised before these details are confirmed.
When is an automatic cap feeding system needed?
The decision depends on cap geometry, orientation, placement method, labor plan and line integration. The feeding system is selected after the real cap and operating process are reviewed.
How are technical parameters confirmed?
Use the specification of the selected Longteng model and validate the application with actual samples. Do not apply a value from another product or project to the current requirement.
Can one machine handle different bottles or caps?
This depends on the selected model, the difference between samples and any required adjustment or change parts. Confirm every bottle-and-cap combination before approval.
