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.
