Paper End Closures
Paper end closures refer to the cardboard lid and bottom glued with round paper discs on both ends.
Why Paper End Closures?
Paper end closures are the most common type of closure used in cardboard tube packaging, whether it involves a one-piece, two-piece, or three-piece tube. This is due to three main reasons:
1. Sustainability. Paper end closures create an all-paper structure, making them fully sustainable and eco-friendly.
2. Flexibility. Unlike plastic or metal closures, cardboard lids and bottoms offer significant customization options. This includes variations in size, printing, finishes, paper stock, and add-ons such as silk pulls or ribbon pulls.
3. Affordability. Compared to metal and plastic lids, the minimum order quantity (MOQ) for paper closures can be as low as 1,000 pieces. This lower unit cost is especially important for startups and small businesses.
Why Not Paper End Closures?
While cardboard closures offer some benefits, there are two drawbacks to keep in mind:
1. Less Durability. Cardboard is not as strong or durable as metal lids and bottoms.
2. Less Airtight. Cardboard lids and bottoms do not provide the same level of airtight sealing as metal closures or membrane closures. If you need exceptional sealing for your tube packaging, a cardboard closure may not be the best option.
