Which type of screw cap is best for your product?

When choosing from various types of screw caps, the first aspect to consider is if the screw cap simply needs to secure the content or if the closure needs to dispense the product. When to choose a standard screw cap If a liquid product just needs to be secured inside the container before being poured out for use, a standard screw cap will suffice. Standard caps and closures are usually fitted with Steran or EPE wads to ensure a good seal. Cambrian stocks standard screw caps in 20/410, 22/410 and 28/410 neck sizes with a heavy rib or fine mill finish. These finishes help the end user grip the cap and also help during application.

These cap taps provide hassle-free dispensing for the end user and are particularly good for the growing refills sector. Use induction heat seals for products which may spoil Induction heat seals are fitted inside the cap during the manufacturing process. When the closure is applied to the bottle after filling, the combination passes under an induction heat device which melts the adhesive on the seal and it adheres to the top of the bottle. This type of seal is usually used where the products are likely to spoil and where biosecurity is important. Cambrian stocks 28/410 neck size induction heat seals, available for both HDPE and PET bottles. Which screw cap is best for a juice bottle?

Best dispensing closures for controlling the flow of liquid When it is necessary to regulate the flow of a liquid product, a dispensing closure is required. Dispensers include disc tops, flip tops, spouts and other specific dispensing closures for particular scenarios. All of these types of dispensing closure allow a product to be dispensed in a controlled fashion, such as a shampoo, polish or lotion etc. Disc tops vs flip tops Disc tops are usually smooth walled, while flip tops can either have a fine mill finish or a smooth finish. Cambrian stocks disc tops in black and white and flip tops in black, white and natural. We have the following sizes available to order for a fast turnaround from stock: 24/410 and 28/410. If liquid contents need to pass through a dispensing closure, they are usually fitted with a bore seal rather than a wad. A bore seal is a vertical element included in the manufacture of the closure, which forms a seal against the inside of the bottle neck. All fliptops and disctops use a bore seal. When to use a spout instead of a screw cap For some products, a spout is more suitable than a screw cap because it allows for more precision in the product application. These are stocked in 24/410 and 28/410 neck formats, some with over caps (to prevent the accidental issue of the product) and some with an integral small cap. Spouts are usually not wadded. What are tamper-evident closures? Tamper-evident closures are used for applications where it is important that the integrity of the contents is maintained. Generally, the format used for this type of closure is a band which binds against lugs on the outside of the bottle neck and tears off when the closure is removed. You’ll be familiar with this type of tamper evident closure from carbonated drinks, and they are also used in the food, automotive, and industrial markets. By opting for tamper evident closures, you can give your product a longer shelf life. 38mm White T/E Cap SKU: ZTU38W What screw caps can you use for child safety? Child-resistant closures are, as the name suggests, designed to be resistant to a child trying to access a dangerous liquid product. The most standard form is a push and turn where the screw cap needs to be depressed and turned at the same time in order to be removed from the bottle, making it difficult for children to achieve and ensuring their safety. TOP TIP! It is sometimes possible to combine child-resistant and tamper-evident closure functionality when necessary, such as in this example : https://cambrianpackaging.co.uk/products/closures/28-pp-white-crc-t-e-cap/
