Poly Bags Wholesale in 2026: $0.04-$0.09 Per Unit, and the Case Count That Actually Matters
Last updated: September 2026
Bottom line: poly bags wholesale run $0.04-$0.09 per unit at standard 1,000-count case sizes; the price swing inside that range comes down to mil thickness and self-seal versus non-adhesive closure, not brand.A 10x13 self-seal mailer from a supplier like Uline typically lands near $0.06-$0.07 each at 1,000 units, while a thinner 1.5-mil bag without an adhesive strip can drop below $0.05.
Buy poly bags wholesale in smaller test quantities first if you have not settled on a size yet — reordering the wrong dimension after a 5,000-unit purchase is a more expensive mistake than paying a slightly higher per-unit price on a first 1,000-count case.
Shipping mailers versus merchandise bagging
Two different products pick up shopped under "poly bags wholesale," and mixing them up wastes money. Shipping poly mailers (the padded or plain envelope-style bag used to ship a garment or small item) run in the $0.04-$0.15 range depending on size and padding.
Merchandise poly bags — the flat, clear bags with a hang-hole used to bag an individual folded shirt or accessory before it goes on a rack or into inventory — are cheaper, often $0.02-$0.04 per unit, because they carry no padding. No adhesive seal.
A reseller shipping directly to buyers on Poshmark or eBay needs the mailer; a reseller prepping inventory for a wholesale lot or a physical storefront rack needs the flat bag.
Ordering the wrong one at 1,000-unit volume is a $20-$60 mistake that is easy to avoid by checking the product description for "self-seal" or "mailer" versus "flat" or "merchandise" in the listing title.
Case size is the other variable that changes the math. A 1,000-count case is the standard entry point most suppliers list, but volume tiers at 2,500 and 5,000 units typically shave another 8-15% off the per-unit price.
A seller moving fewer than 100 units a month rarely benefits from jumping straight to the 5,000-count tier — the cash tied up in inventory that will not turn for six months outweighs the per-unit savings, especially for a size or thickness that has not yet been tested against actual order volume.
Poly Bags Wholesale Cost Table: $50-$90 Per 1,000-Unit Case, Freight Included
Bottom line: a 1,000-count case of poly bags wholesale lands at $50-$90 delivered once freight is added, and the per-package cost drops to $0.02-$0.04 per shipment once you factor in how multiple units a single mailer actually covers.The table below breaks out every line on a typical invoice for a mid-size 10x13 self-seal mailer order from a supplier such as Uline.
| Cost component | Low estimate | High estimate | Notes |
|---|---|---|---|
| Poly bags wholesale, base unit price (1,000-count case, 10x13 self-seal) | $45 | $70 | 2-mil thickness, standard opacity |
| Freight to a domestic address | $5 | $15 | Ground shipping, varies by supplier zone |
| Subtotal, landed per case | $50 | $85 | 1,000 units |
| Per-unit cost | $0.05 | $0.085 | Landed price divided by case count |
| Volume discount at 5,000 units | -8% | -15% | Applied against base unit price, rule of thumb |
| Total cost at 5,000-unit tier | $230 | $360 | Roughly $0.046-$0.072 per unit landed |
Where the per-unit price actually moves
Thickness is the biggest single lever on poly bags wholesale pricing. A 1.5-mil bag costs 15-20% less than a 2-mil bag of the same dimensions. It also punctures more easily in transit — a real cost if it shows up as damaged-item returns rather than as a lower packaging line item.

A seller shipping heavier apparel, like denim or outerwear, should stay at 2-mil or higher; a seller shipping lightweight items like t-shirts or accessories can often drop to 1.5-mil without a meaningful increase in damage claims.
Self-seal adhesive strips add roughly $0.005-$0.01 per unit over a non-adhesive bag that requires tape, but they save 3-5 seconds of packing time per shipment.
At a volume of 500 shipments a month, that time savings is worth more in labor than the adhesive strip costs — a buyer packing fewer than 50 shipments a month may not see the same return and can save the small per-unit premium by taping instead.
Freight is the line most buyers underweight when comparing quotes for poly bags wholesale across suppliers. Since a case of poly mailers is light but bulky, the shipping cost is driven more by box dimensions than by product weight.
A supplier depot located far from a buyer's zip code can add $10-$15 to a case that would cost $5 to ship from a closer warehouse.
Checking whether a supplier has a regional distribution center near you — Uline, for example, operates multiple depots across the US — often closes a meaningful chunk of that freight gap without changing the product at all.
A second or third supplier quote, checked once a quarter, is a five-minute task that regularly turns up a $5-$10 freight difference on the exact same case. , according to U.S. wholesale trade data from Census Bureau

Poly Bags Wholesale: The 4 Specs Experienced Buyers Check Before They Order
Bottom line: a buyer who checks mil thickness, suffocation-warning compliance, actual measured dimensions; seal strength before ordering avoids the roughly 10-15% of complaints that come from a poly bag that technically matches the listing but fails in practice.A first-time buyer of poly bags wholesale reads the headline size and price and stops there; an experienced buyer treats those two numbers as a starting point and verifies four more things before agreeing to a case.
The four checks that separate a favorable order from a returned one
- Mil thickness, stated explicitly.A listing that says "heavy duty" without a mil number is a red flag — request the spec sheet. Standard shipping mailers run 1.5-3 mil; anything sold as poly bags wholesale without a stated thickness should be treated as unverified until confirmed.
- Suffocation-warning compliance.US federal guidance and several state laws require a printed child-safety warning on plastic bags above roughly 5x5 inches intended for retail or shipping use. A supplier who cannot confirm their poly bags wholesale product carries compliant labeling exposes the buyer to liability, not just an aesthetics issue.
- Measured dimensions, not just the printed size.A "10x13" mailer can vary by a quarter-inch between manufacturers due to how the bag is measured (flat versus filled). Ordering a 5-10 unit sample and measuring it against your actual product before signing up for to 1,000+ units catches a fit mismatch before it becomes a bulk problem.
- Seal strength under realistic conditions.A self-seal adhesive that holds in a climate-controlled warehouse can fail in a hot delivery truck. Buyers who ship through summer months in southern states report seal failure rates as high as 3-5% on lower-grade adhesive versus under 1% on name-brand supplies from a source like Uline.
The dimension check matters more than it sounds for resale sellers specifically, because a poly bag that is even a half-inch too small forces the item to stretch the seal, which raises the failure rate covered in the fourth checklist item above.
A seller bagging a mix of product types — folded shirts, shoes in a box, an accessory — needs at least two or three sizes of poly bags wholesale on hand rather than trying to force every item into one size purchased in bulk because it was the cheapest per-unit option.
Suffocation-warning compliance is the check most first-time buyers skip entirely, and it is also the one most likely to matter beyond cost. A supplier selling poly bags wholesale into the US market without the required warning label is either targeting a implement case exempt from the requirement (an internal packaging application, for example) or is not fully compliant —.
A reseller shipping directly to consumers should confirm which is true rather than assume compliance since the price looked competitive. This is a five-minute question to a supplier's sales team, and any supplier unwilling to answer it directly is a signal to keep shopping.
What "experienced" actually looks like in practice
An experienced buyer of poly bags wholesale keeps a running log of which supplier. Which SKU corresponds to which failure rate, rather than treating every reorder as a fresh decision. After two or three case orders, that log turns into a simple rule: reorder the supplier.
Thickness that produced under 1% seal failure and under 2% dimension complaints; drop any supplier that crossed those thresholds even if the per-unit price was lower.
That discipline is worth more over a year of ordering than any single negotiated discount, because a $0.01 per-unit savings on a bag that fails 4% of the time costs far more in replacement shipments. Customer-service time than it saves on the invoice.
Poly Bags Wholesale: Common Questions Before Your First Case Order
Bottom line: the questions below cover the specs, compliance, and reorder logic buyers most often demand answered before they commit to a first case of poly bags wholesale.
What thickness of poly bags wholesale should I buy for clothing?
For most folded apparel and light accessories, 1.5-2 mil is standard and holds up through normal handling. Heavier items like denim, boots, or a stacked multi-item shipment do better at 2-3 mil. If you are unsure, order a small sample of both and test them against your actual product rather than guessing from the listing description alone.
Are poly bags wholesale required to have a suffocation warning?
In most cases, yes. US guidance and several state laws require a printed child-safety warning on plastic bags above roughly 5x5 inches sold for retail or shipping implement. Ask any supplier directly whether their poly bags wholesale product carries compliant labeling before ordering at case volume — a legitimate supplier answers this question without hesitation.

How many poly bags wholesale come in a standard case?
Most suppliers set the entry tier at 1,000 units per case, with volume discounts of roughly 8-15% kicking in at 2,500 and 5,000-unit tiers. A seller shipping fewer than 100 packages a month typically does not need to go past the 1,000-unit tier on a first order.
Do self-seal poly bags cost more than tape-seal versions?
Yes, by roughly $0.005-$0.01 per unit, but the time saved packing — 3-5 seconds per shipment — usually pays for that premium once monthly volume clears about 150-200 shipments. Below that volume, taping a non-adhesive bag can be the more cost-effective choice.
Where can I check current poly bags wholesale pricing?
Suppliers such as Uline publish current case pricing online; prices shift with resin costs several times a year. Confirm a live quote before finalizing a margin model, since a price seen in an older listing or article may no longer be accurate.
Can I mix sizes in one poly bags wholesale order?
Most suppliers price by size and thickness combination, so a mixed order usually means placing separate line items rather than one blended case.
A seller handling varied inventory — shirts, shoes, accessories — commonly keeps two or three sizes in stock rather than forcing every item into one size purchased at the lowest per-unit price, since an oversized or undersized bag raises the seal-failure and return rate covered earlier in this guide.
Poly Bags Wholesale: Order a 1,000-Unit Test Case Before You Scale
Bottom line: start any new poly bags wholesale relationship with a 1,000-unit test case, track seal failure and dimension accuracy for 30-60 days, and only step up to the 5,000-unit discount tier once that data confirms the supplier and thickness hold up under your actual shipping conditions.Skipping straight to bulk pricing on an unverified supplier is the single most common way sellers end up sitting on 4,000 unused bags in the wrong size or thickness.
Building the check into your ordering routine
Set a recurring 90-day reminder to re-quote your poly bags wholesale supplier rather than reordering on autopilot.
Resin costs and freight both shift over the course of a year; a supplier that was competitive at $0.06 per unit in January can drift 10-15% higher by fall without an active buyer noticing, since most reorders happen from a saved cart rather than a fresh price check.
Sellers running a crosslisting operation across multiple marketplaces can track packaging cost per shipment alongside their sell-through data to see exactly how a $0.01 per-unit change in poly bags wholesale pricing moves overall margin at scale. For related sourcing guides on shipping and packaging decisions, see the Closo blog center.
The math in this article — $0.05-$0.09 per unit at 1,000 units, dropping to roughly $0.046-$0.072 at 5,000 units — is a starting model, not a quote. Freight, resin cost; regional supplier availability all move the real numbers a specific buyer sees, sometimes by 10-20% in either direction.
Treat every range here as the baseline to check your own quote against, not the number to build a final margin plan around before confirming it with an actual supplier.
