Blocks All MoistureDirect from China Factory

Custom Dishwashing Block Bags: Block Moisture. Keep Your Products Dry.

Tough packaging built for solid detergent blocks. We test these against high pH levels (10-13) so they won't break down. They run smoothly on fast FFS filling lines. We use similar materials for our soap packaging pouches and laundry detergent bags. You buy direct from our China factory with 7 to 12 day production. We handle all shipping and customs—you pay one invoice, and we deliver to your door.

Built to Block Moisture and Stop Chemical Reactions

Dishwashing blocks break down if they catch any humidity in the air. We build our packaging to block moisture completely, protecting your product from the day we make it until your customer uses it in their kitchen.

Vapor Guard Barrier Technology

Blocks All Moisture

Moisture ruins dishwashing blocks before they even reach the store. We use special film layers that block water vapor entirely. This keeps the air inside dry and stops your blocks from cracking for over 2 years.

Anti-Alkaline Lining Integrity

Handles High-pH Formulas

Strong chemicals like sodium carbonate eat through standard plastic bags. We line our bags with a tough, high-density resin that blocks these chemicals. The bag won't peel apart, and it keeps your scents smelling fresh.

Structural Puncture Defiance

Stops Corner Punctures

Hard powder blocks have sharp corners that poke holes in cheap bags during shipping. We press multiple heavy-duty layers together to make a tough bag. This stops the blocks from tearing the corners or breaking the seals.

Why Factory-Direct

What You Get Buying Direct from the Factory

No middleman markup. No 8-week waits. No customs surprises. Here's what changes when you buy direct.

Advantage #1: Speed

7-12 Days: Your Bags Land Before Local Suppliers Even Start

Local packaging brokers often make you wait 6 to 8 weeks and charge a big markup. We make your bags in our own 20,000㎡ facility. Because we run our lines 24/7, we finish your custom bags in 7 to 12 days. Add 7 to 10 days for sea shipping, and you receive your bags before a local broker even starts printing.

7-12 Day Production for Dishwashing Block Bags
Eco Materials for Dishwashing Block Bags
Advantage #2: Material

Eco Bags That Stay Together Under High pH

Many eco-friendly bags fall apart when they touch strong alkaline detergents (pH 10-13). The layers just split after a few weeks. We build our Recyclable Mono-PE and compostable PLA bags with an mPE inner layer that blocks chemical reactions. Your bags keep their shape and won't peel. We test them to meet FDA and EU standards.

Advantage #3: Sampling

Test on Your Machines Before You Pay

We mail you free stock samples within 48 hours. You can run them on your machines and do drop tests to see how they perform. If you want a sample printed with your design, we do that too. We subtract that sample cost from your final order when you go into production.

Free Samples for Dishwashing Block Bag Verification
DDP Delivery for Dishwashing Block Bags
Advantage #4: Logistics

Door-to-Door Delivery: One Price, No Customs Headaches

We quote you a single Delivered Duty Paid (DDP) price. This pays for everything: making the bags, shipping them across the ocean, clearing customs, paying duties, and driving them to your door. You pay one invoice. You won't deal with port fees or customs brokers.

Buyer FAQ

Questions from Detergent Brand Buyers

Chemical compatibility, EPR compliance, multi-SKU sampling, DDP scope — questions we actually get from procurement teams.

Standard bags use glue that breaks down when it touches high-pH products. You will see the layers peel apart in just a few months. We fix this by fusing the bag layers with heat, not glue. We add a tough mPE inner layer that blocks the chemicals. Since we don't use glue, the high pH has nothing to destroy. We pack pH 13 blocks in these bags and they stay intact for over a year. Send us your safety data sheet (MSDS), and we will check your formula before we quote.
Yes. EPR rules mean you need recyclable or compostable bags, but those bags still need to run fast on your packing lines. We make our Mono-PE and PLA bags smooth enough (COF 0.15-0.25) so they don't jam your machines. We send you the layout files to set up your machines, and we mail you free test rolls so you can try them before you buy. Just tell us if your machines run faster than 60 bags a minute, and we will make the film stronger.
Local brokers charge you a big markup and make you wait 6 to 9 weeks because they buy from factories like us. When you buy direct, you cut out the middleman. You pay the factory price and get your bags in 7 to 12 days. You talk directly to the people making your bags. For quality, we use third-party companies like SGS to inspect every shipment. We can even show you a live video of your bags on our production line before we ship them.
No. We use digital printers for smaller orders, so we don't charge you for printing plates. You pay for the material we use, not the number of designs. You can print all 5 scents in one run and meet just one minimum order quantity. If you buy in large volumes (more than 3,000 per scent), we switch to traditional printing to save you money. We run the numbers and show you the cheapest way to print.
You have two choices. First, we send you free stock samples within 48 hours. These bags use the exact same material you will order. You can drop them, test them on your machines, and check if they block moisture. Second, we can print a small batch with your design. We charge for this, but we credit that money back to you when you place your full order. Many buyers do both: they test the free stock bags first, then order a printed sample to check the colors.
Our DDP price covers almost everything. It pays for making the bags, packing them, shipping them over the ocean, clearing customs on both sides, paying trade duties, and driving the truck to your warehouse. The only thing it might not cover is your local VAT or GST tax, because some countries handle that differently. We look up the tax rules for your exact address and tell you before you pay anything.
