Although it is nearly difficult to list every kind of cap that exists, these are the thirteen most common kinds that you might run into. Knowing them will enable you to choose the best solution for your product and guarantee that your capping equipment can handle them.
Typical Screw Cap: Though there are many variations, the most common type of screw caps and lids are the standard ones. These straightforward caps serve the primary function of enabling customers to unscrew, drain the contents, and then screw them back on tightly. Screw caps, which are frequently composed of plastic or aluminum, are used to preserve a variety of goods, including big chemical barrels, soft beverages, honey jars, and tiny pharmaceutical vials
Childproof caps: Children are prevented from opening bottles of potentially hazardous items like motor oils, chemical cleaning solutions, and medications by the safety mechanism of this screw cap. You compress the sides or press down on the cap to safely open it. Your automatic capping machine will need to handle this kind of closure, of course.
Top-Flip Caps: A different type of screw cap is the flip-top lid, which is frequently used for squeezable containers with the cap stowed down. Sauces, toothpaste, and shampoos are a few items that use this kind of cap. The caps have a flip lid that closes to keep the contents fresh and a little hole in the middle that lets the product flow. Flip tops, like regular screw caps, can have a plastic or foil seal within them. Similar to flip-top lids, flip spouts only have a portion of the cap that flips upward to create a practical nozzle for directing the product.
Press-top or disc-top cap: The disc cap works similarly to a flip top, with the exception that when you press down on one side, the other side rises to reveal the hole where the product is released. Shampoos, face creams, sun creams, and other personal care items frequently have disc top caps on them because they are convenient to open with wet or oily hands.
Push-pull caps and sports caps: Sports caps are a type of screw-top cap with an upward-pointing nozzle that you pull to open and discharge the product. Because you may activate the nozzle with your teeth while cycling or jogging, sports drinks frequently employ them. The majority come with a plastic cover to shield the nozzle.
Heads that Trigger: You're probably familiar with the common trigger heads that let you push the trigger to discharge a product spray or jet. They are frequently used for cleaning supplies like window cleaner and bathroom spray as well as garden supplies like plant food and weed killer. To avoid unintentional discharge, the majority have a locking mechanism that allows you to twist either the nozzle or the entire cap. Trigger heads are widely used, however, because they require side tightening, capping machines may find them challenging to operate. Moreover, their caps frequently jam feeding systems and hoppers.
Caps for pumps: Pump caps have a dispenser that, when depressed, releases liquid or cream; the dispenser is locked in place by twisting the pump. Because they reduce touch, they are well-liked for hand soap, hand sanitizer, shampoo, and sunscreen. They can be cumbersome and cause issues for feeders and capping equipment, such as trigger caps.
Top Cap with Twist: Typically, twist-top caps have a hole at the top that, when the nozzle is twisted to open the hole, allows the product to flow. Sauces often have twist tops, particularly mustard.
Roll On, Pilfer Proof Caps: For goods like spirits and liqueurs, where tampering may be an issue, ROPP caps are helpful as they offer an airtight seal for sparkling wines. To create a tamper-proof seal, the capping machine uses this method to force a blank aluminum cap onto the bottle's threaded neck.
Corks: Even wine enthusiasts are familiar with corked bottles. A capping machine, which can be made of plastic or cork, applies pressure to force the cork into the bottle, creating a tight seal. The neck and top of the bottle are then covered by a plastic shrink-wrap sleeve that machines apply to the majority of items.
Polyethylene (PE): This type of plastic is frequently used to make bottle caps. HDPE caps are well-known for being strong and resistant to chemicals and moisture, which makes them ideal for a variety of uses.
Polypropylene (PP): is another material that is frequently used to make bottle caps. It provides good temperature resistance, chemical resistance, and strength. For products like fizzy drinks that need a tight and safe seal, PP caps are frequently utilized.
Polystyrene (PS): Often used for bottle caps, polystyrene is a stiff, lightweight plastic substance. It is used in juice and water bottle tops and is renowned for having outstanding clarity.
Polyethylene terephthalate, or PET: PET can be used to make bottle caps, but it's more frequently employed to make plastic bottles. PET caps are clear, lightweight, and offer a strong defense against chemicals and impacts.
Polyvinyl chloride: is a multipurpose plastic occasionally utilized to make bottle caps. It provides exceptional durability and chemical resistance. PVC is used less frequently than other materials, though, because of worries about how it would affect the environment.
