Custom flexible packaging is quoted based on product type, size, material structure, thickness, printing colors and order quantity. Reference price: from US$0.07/pc. Actual quotation may vary by specification. For an accurate quotation, please contact Huasheng Packaging with your size, material, quantity and artwork.
Material Structure Options
Side Gusset Bag Buyer Decision Matrix — Buyer input: product density, fill weight, target filled dimensions, flat width, gusset depth, cut length, seam and closure, barrier target, valve or zipper, artwork and filling process. Factory review: filled profile, seam layout, laminate direction, feature clearance and equipment fit. Release evidence: signed construction drawing, approved artwork, representative filled sample, agreed seal or barrier checks and documented handover specification. These decisions should be reviewed together rather than approving the bag from a generic size or material name.
Application Recommendations
PET/PE (general dry food packaging with good sealing and print surface). PET/VMPET/PE (improved moisture and light barrier for premium dry food). PET/AL/PE (high barrier for aroma and oxygen protection; suitable for coffee and shelf-stable products). Kraft/VMPET/PE (natural kraft appearance with barrier support for organic or premium brands). PA/PE (puncture resistance and flexibility for heavier products). Final structure confirmed based on product type, filling weight, gusset width, shelf life and storage conditions.
Side Gusset Structure and Bag Options
Coffee: PET/VMPET/PE or PET/AL/PE with side gusset for larger bag format and aroma protection. Dry food and grains: PET/PE or PET/VMPET/PE with expandable gussets for bulk packaging. Powder products: PET/AL/PE or PET/VMPET/PE with moisture barrier and strong sealing. Pet food: PA/PE or PET/VMPET/PE with puncture resistance for kibble. Tea and dry herbs: PET/VMPET/PE or Kraft/VMPET/PE with aroma protection and natural appearance option.
Quality Control Points
Side Gusset Bag Construction — A side gusset bag expands through two folded side panels and commonly uses a back or center seam with a top or bottom closure. A quad seal bag instead has four vertical corner seals around the gussets, while a flat bottom pouch has a separately formed rectangular base. Confirm the construction drawing, seam position and finished dimensions because these names are sometimes used inconsistently in sourcing discussions.
MOQ and Cost Notes
Dimensions, Artwork and Filling Fit — Specify flat width, gusset depth, cut length, headspace and target filled dimensions rather than filling weight alone. The back or center seam, gusset folds, valve, zipper and sealing areas affect the usable artwork space. For machine packing, also confirm feeding method, sealing jaws, registration mark, product drop and required coefficient of friction. Validate the filled profile and closure with a representative sample.
What to Prepare Before Requesting a Quote
Each batch undergoes side gusset forming check, sealing strength test, bottom stability verification, print registration inspection, barrier performance test, load-bearing check for larger bags and size tolerance measurement. Pre-shipment inspection with retained batch samples. ISO22000 certified production.
Quality and Certification
MOQ depends on bag size, gusset width, material structure, thickness, printing colors and order quantity (typically from 30,000 pcs). High-barrier or kraft structures cost more than basic film structures. Larger bags require stronger sealing and thicker material. For accurate quotation, please send product type, filling weight, bag size, gusset width, material preference, printing colors, quantity and artwork.

Material Structure Options
Q: What is a side gusset bag? A: It is a flexible bag with two expandable side panels, commonly combined with a back or center seam. Q: Is a side gusset bag the same as a quad seal bag? A: Not always. Quad seal construction uses four vertical corner seals; confirm the drawing and seam layout. Q: How is it different from a flat bottom pouch? A: A flat bottom pouch has a separately formed rectangular base, while a conventional side gusset bag relies on folded side panels and its closure construction. Q: Can side gusset bags include a valve or zipper? A: These features may be available when dimensions, film, seam position and packing process are compatible; confirm with artwork and a representative sample.

Buyer Notes
- Provide product type, bag size or roll width — a photo or sample helps quick assessment
- If material structure or thickness is known, include specification
- Number of printing colors and artwork file affect cylinder cost and prepress time
- Packing machine type (VFFS/HFFS/manual) determines roll film vs premade pouch choice
- Target market compliance, China OEM filling requirements or nominated domestic warehouse handover details help confirm the final specification

Can Huasheng Packaging provide samples?
Yes. Existing production samples can be provided for material and workmanship reference. Custom printed samples, structure samples or pre-production samples should be confirmed by project according to artwork, size, material and printing colors. Sample method, timing and cost are confirmed before order placement.
What is the lead time for custom packaging orders?
Typical lead time is 15-25 working days after artwork confirmation and deposit receipt. Exact lead time depends on material structure, order quantity, printing complexity and current production schedule.
What material structure should I choose?
Material structure depends on product type (dry, oily, frozen, liquid, high-temperature), shelf life requirements and packaging machine type. Common options include PET/PE, PET/VMPET/PE, BOPP/CPP, NY/PE and kraft paper laminates. We can recommend suitable structures based on your product details.
What is the difference between roll film and premade pouch?
Roll film is printed laminated film supplied on rolls for automatic packing machines (VFFS/HFFS), where filling, forming and sealing happen on one machine. Premade pouches are pre-formed bags delivered ready for filling on separate equipment. The choice depends on your production line and product format.
