Switory Parcel Bags Mailing 14x19 inch self-seal waterproof postal bags (100 pack) – Grey
Product description
If you regularly post parcels, a stack of reliable mailers can save time and headaches. Switory’s Parcel Bags Mailing are plastic postal bags in a 14 x 19 inch size, supplied as a 100-pack, with a self-seal strip designed to close quickly and stay secure.
On paper, they’re built for everyday dispatch work: they’re described as waterproof and resistant to oil, with a construction of polyethylene-type materials meant to stand up to rough handling. They’re also positioned as multipurpose, covering everything from posting clothes to packing smaller goods like electronics and home items.
The essentials (what these bags are for)
These are self-sealing poly mailers for sending items through the post. The 14 x 19 inch format makes sense when you’re shipping flat-ish products or smaller parcels where a rigid box feels like overkill. The appeal here is the workflow: fill the bag, peel the strip, seal it, and you’re done.

A small “micro-use” example: imagine you’ve got a handful of T-shirts or folded items to send. Instead of taping every edge, you can slide them in, press the adhesive closure together along the seam, and finish packing in minutes. For sellers and offices that dispatch repeatedly, that sort of speed matters.
Key takeaways (what stands out)
A few things look particularly useful based on the description provided:


- Self-seal with pressure-sensitive adhesive: the bags are described as easy to use and designed for a secure, tamper-resistant closure.
- Waterproof and oil-resistant: they’re meant to help protect contents from rain and everyday grime during transit.
- Multipack value: you’re getting 100 bags in this size, which typically suits regular shipping batches rather than occasional use.
- Durable polyethylene-style build: the material is claimed to be robust enough for shipping wear and tear.

It’s also worth noting that Switory mentions several sizes across its range. This particular listing is for the 14 x 19 inch bags, so if your items consistently need a different footprint, you’ll want to check that you’re picking the right size.
What you’ll notice day to day (realistic strengths and limits)
In day-to-day use, the main benefit of mailers like these is convenience. Self-seal closures reduce the amount of tape work, and a waterproof outer layer can provide peace of mind when the weather is unpredictable.
That said, there’s a limitation you should consider: plastic mailers are only as protective as their fit. If an item is bulky, sharp-edged, or doesn’t sit comfortably inside, you may still need extra padding or a separate wrapping approach to avoid stress on the bag. Also, the bag size (14 x 19 inch) may be a perfect match for some categories, but it could be tight for thicker parcels or anything that needs more clearance.

Worth considering if you prioritise lightweight dispatch and fast packing. If you’re shipping something that truly requires rigid protection, you may find boxed packaging is the more reassuring route.
Quick sizing guidance (getting the size right)


This pack is for 14 x 19 inch postal bags. Before buying, measure your typical items (or the packed dimensions) rather than relying on the item’s name. Clothing can vary massively in thickness depending on fabric and how tightly you fold it.
If you switch between different product types, it can help to keep an eye on your most common packed size. Switory’s description suggests they offer multiple dimensions in their broader range, so you likely won’t be stuck if you need a different size later—just make sure you’re choosing the right listing for the dimensions you need.

Care & maintenance
These are described as waterproof and resistant to oil, which is helpful for transit. Beyond that, there isn’t much “care” to manage: you’re mainly using them as disposable shipping protection. If you store them, keep them somewhere dry and away from heavy abrasion so the adhesive area stays clean and ready to seal.
When it makes sense?
It’s a good fit if you ship regularly and want a practical 100-pack of self-seal, waterproof plastic mailers for clothes and smaller goods, especially when speed of packing and weather protection matter.

You may want to skip it if your parcels are often bulky, sharp, or require rigid, drop-proof protection. In those cases, a padded wrap plus mailer (or a more structured packaging approach) may be more suitable, depending on what you’re sending.


Also, double-check the 14 x 19 inch size against your most common items—mailers are great, but the wrong size can be frustrating even if the bag itself is well made.
