Our black matte polypropylene plastic caps are offered in a variety of sizes and all come with PE liners. The PE liner is a good general-purpose liner that has a broad application base and strong chemical resistance. It is also a good choice for acids, alkalis, solvents, alcohols, oils, household cosmetics, and aqueous products. The plastic caps are ribbed for a better grip when twisting the cap on and off.
To add items to your cart from the product page, enter a quantity in full bags/cases of each item you would like to purchase.

You will be directed to the shopping cart page to either continue shopping or complete your order.
Product Price: The price listed is the full price for 1 case or bag of the item. When hovered over, the price displayed is converted to the cost per piece for your reference.
Case Pack The case pack lists how many items are received for the price listed. For example, a kit of glass jars with metal caps with a case pack of 12/cs will include 12 glass jars with 12 caps. Enter how many full case packs you would like to purchase in the Qty field.
Quantity If you are ready to purchase the products, enter how many cases or bags you would like to purchase and click Add to Cart. This field will only accept whole numbers (full case packs).

Product addons are compatible items that can be added to your container to complete your product's packaging design. This can include compatible closures, labels, shrink bands and more. Click the icons next to a stock number to see an expanded list of compatible addon items for easy shopping. If an add-on item is available in multiple case packs, all case options will be grouped together for easy comparison and ordering.
The green Addon circle provides a list of compatible closures when viewing a container
The pink Addon circle provides a list of compatible containers when viewing a closure
The orange Addon circle shows all of the compatible shrink bands for the containers.
The blue Addon circle indicates various custom labels SKS has to offer to match the containers.
Add any Addon item to the shopping cart by adding the full case/bag quantity desired to the Quantity box directly next to the Addon. You will be directed to the shopping cart to review the additions you have made.
If products do not have Addon icon next to them, SKS does not have compatible items for that container's specific size and shape.
There are a few reasons why shrink bands may not be available with some containers:
Shrink bands are not compatible with a specific container style.
In some situations, containers will have measurements that seem compatible with shrink bands listed. The containers' shape, neck, or shoulders are still unsuitable for forming a tamper evident seal once applied.
The caps paired with the containers are not compatible with shrink bands.
Some of these caps can include lotion pumps, or some twist top caps and bulb glass droppers.
The correct size is not available.
Shrink bands must be within a specific millimeter range of the container diameter to work correctly. Shrink bands that are too small will tear on the perforation before sealing, and shrink bands that are too big will not correctly shrink to the containers' shape.
Out of Stock Items
If an item is currently out of stock, you will see "Out of Stock" with an approximate arrival date below the stock number in the product table. If the product does not have an estimated arrival date in our system, it will display as "TBD" until a purchase order is entered in our system. Below this note, you will also see the "Notify Me When Available" button, which will open a form in a pop-up window. Simply enter an email address to be alerted when that particular product returns to stock.
Placing an order for out of stock items will add your order to the waitlist for fulfillment when stock returns. Any products included in the order that are available to ship will be shipped in SKS' standard processing time and will not be held back by the out of stock items, unless you choose the "Group Shipment" option during checkout, which will hold all items until they can be shipped together.
Cases in Stock Information
Items that currently have 10 or less cases available in stock will also show an indication of the amount left with an "Order Now" alert in orange text.
Email for Quote Items
If there is an Email for Quote notation listed against an item you are interested in, you cannot add this item to your shopping cart. These items are available, but have a minimum purchasing requirement. Instead, you will be directed to a form that will begin the quoting process and is sent to our Customer Care department once filled out and submitted.
The size listed is in liquid measurements for containers. If you are unsure which size is appropriate, place an order for samples, and test with your product.
Dimensions All dimensions are listed in millimeters (mm). When hovered over, the measurements convert into inches for your reference. The height listed for kits includes the height from the container base to the top of the closure. The height listed for bulk containers sold without caps is the height of the container itself.
Neck Finish Many measurements are used to establish a neck finish for each container and closure. The neck finish helps determine compatible sets of containers, closures, and additional components, including shrink bands, orifice reducers, and more.
