The Complete Guide how to Ordering Plastic Bags from GPS (8 Steps — No Guessing, No Trial and Error)

New customers who haven't ordered plastic bags from the factory before tend to ask the same questions over and over — things like "How do I describe the spec so the factory understands exactly what I mean?" or "What do I need to prepare for a first order?" This article rounds up all 8 steps our GPS team actually uses to take orders every single day, covering everything from choosing the bag type through to the information needed for a quotation. Read it once, and you can place your order right away — no need to call and ask the same questions over and over.

Step 1: Choose the "Bag Type" First

Tell our team the shape you want first — then we'll help you choose the material, size, and thickness.

• Handle Bag — Has handles with side gussets. Strong load capacity. Thickness measured "×4" (four layers)

• Flat-Cut Bag — Straight open top, sealed bottom. General purpose use. Thickness measured "×2" (two layers)

• Plastic Roll — Film on a roll — cut it to size yourself as needed. Order by weight or width

Step 2: Choose the "Material"

Materials differ in feel and use — get this right before anything else.

• HD (crisp texture) — Crisp with a light rustling sound. Thin yet strong, holds weight well, tear-resistant. Best for handle bags, grocery bags, and dry goods (not for cold storage)

• PE (soft texture) — Soft, stretchy, glossy and clear. Stretches without any rustling sound. Best for liquids, freezing, or jobs needing clarity

• PP (hot-fill bag) — Clear, rigid, and glossy. Heat resistant. Can hold hot food or hot items

Step 3: Choose the "Size" — Made from 5"–150"

Minimum order quantity (MOQ) depends on the size you choose:

• Small sizes 5"–10" — MOQ 300 kg and up

• Large sizes 10" — MOQ 150 kg and up

Step 4: Tell Us the "Intended Use"

Heavy items? Need freezing? Just a dust cover? Let our team know — we'll help you pick the material and thickness that gives you the best price and the right quality for the job.

Step 5: Get the "Thickness" Measurement Right

Bags with side gussets (like handle bags) are measured at a different point than flat-cut bags — so the thickness reading differs. Make sure you measure the right spot.

• Handle bag (has side gussets) — measured at the side, at the gusset fold. Thickness ×4 = 4 layers

• Flat-cut bag — measured at the center, all the way through. Thickness ×2 = 2 layers

• Measuring a single sheet only (per side) — Thickness ×1 = 1 layer

Step 6: Choose the "Resin Grade"

The lower the grade, the lower the price. Choose based on your budget and the job at hand.

• Food Grade (FOOD) — New pellets. The clearest, cleanest, food-safe option

• A1 Recycled — Still fairly clear. Secondary grade, not for food contact, lower cost

• AB Recycled — Starting to turn hazy. More economical than A1

• Grade B — Quite hazy. General-purpose use, budget price

• HD C Colored — Color pigment added (red/green/blue) for trash bags

• Grade C — Tea-tinted clear. The most economical option

• Solid Black Trash Bag (recycled) — Cheapest option in the lineup

A note on made-to-order production: Customers accept all production scrap, and the actual delivered quantity may run ±10% over or under the order — this is standard practice for made-to-order production.

Step 7: Choose the "Packing Style"

Our team hand-packs every single bag, and weighs every order for real before it ships.

• Handle bags — packed at half a kilogram (½ kg) or 1 kg per pack other than this, we wont include

• Black trash bags — packed at 1 kg per pack, wrapped in a free colored poly sleeve

• Tied / folded style — bundled at 1 kg per bundle, then packed into sacks at 25–30 kg per sack

Step 8: Prepare Information for a Quotation

So our team can prepare your quotation as fast as possible, have the following ready in advance:

• Company name and address (for issuing the tax invoice)

• Tax ID number

• Delivery address (if different from the company address)

• Phone number and email for follow-up
