Stretch Wrap Film Manufacturer China: OEM, MOQ & Grade Guide

Why Factory-Direct Sourcing Changes the Math for Stretch Film Buyers

Stretch wrap film is a high-volume, low-margin consumable. Procurement managers in logistics, food manufacturing, and distribution buy it by the pallet or by the container — and a $0.30/kg difference in unit cost adds up to tens of thousands of dollars per year at scale.

Buying factory-direct from a Chinese LLDPE stretch film manufacturer eliminates two to three layers of middlemen. The typical price chain looks like this:

• Factory FOB price: $1.20–1.60/kg for standard 20 micron hand stretch film
• Trading company markup: +15–25%
• Import distributor margin: +20–35%
• End-buyer price from local stock: $2.10–2.90/kg

For a buyer importing a 20-foot container (≈14 MT), the difference between factory-direct and distributor pricing is often $9,000–18,000 per shipment. That’s the business case for working with a verified Chinese stretch wrap film manufacturer.

China accounts for roughly 38% of global LLDPE stretch film production capacity, concentrated in Zhejiang (Ningbo/Cixi region), Guangdong, and Shandong. SUNWRAP’s production base in Ningbo means FOB transit times of 25–28 days to Rotterdam, 18–22 days to Dubai, and 15–18 days to Port Klang — competitive across every major import market.

Machine Stretch Film vs Hand Stretch Film: Specification Comparison

These two product types serve different operational contexts, and understanding the spec differences prevents costly sourcing mistakes.

Specification	Machine Stretch Film	Hand Stretch Film
Gauge (micron)	12–17 µm standard; up to 23 µm heavy-duty	17–23 µm standard; 8–12 µm pre-stretched
Roll width	500 mm (19.7”) standard; 450–750 mm custom	400–500 mm standard; 250–600 mm custom
Core ID	76 mm (3”) — turret machine compatible	38 mm (1.5”) or 50 mm (2”) — hand-grip cores
Roll length	1,500–3,000 m per roll	200–500 m per roll
Typical application	High-speed automated pallet wrappers (≥20 pallets/hr)	Manual pallet wrapping, bundling, surface protection
MOQ per pallet	~500 kg (approx. 30–40 rolls)	~500 kg (approx. 100–120 rolls)
Pre-stretch capability	Yes — up to 250% pre-stretch on cast LLDPE	No (hand film not pre-stretched in production)
Puncture resistance	Higher (thicker gauge, metalocene LLDPE option)	Moderate; upgrade to nano-layer for sharp-edged loads

Key decision rule: If your customer uses a turret or rotary arm wrapper and wraps more than 15 pallets per shift, specify machine stretch film with 76 mm core. For ad-hoc manual wrapping in warehouses or retail back-of-house, hand film with 38 mm core is standard. Ordering the wrong core ID causes operational downtime — this is one of the most common sourcing errors we see.

Stretch Film Grades: LLDPE Types and What They Mean for Your Order

Not all LLDPE is the same. Chinese manufacturers work with several resin grades that determine performance, price, and compliance status.

Food-Grade LLDPE (C4 or C6 Metallocene LLDPE)

Used for direct food contact — wrapping fresh produce, meat trays, cheese, and baked goods. Compounded from virgin LLDPE resin (Dow, LG Chem, Sinopec grades) certified to:

• FDA 21 CFR §177.1520: Olefin polymers permitted for food contact
• EU Regulation No 10/2011: Plastic materials and articles intended to contact food
• Total migration limit: ≤10 mg/dm² (EU standard)

Typical specs: 12–17 µm, clear, high-cling, tensile strength ≥25 MPa, elongation at break ≥450%.

Price premium vs. industrial grade: +8–12% per kg. Always request a lot-specific migration test certificate, not just a factory-level declaration.

Industrial LLDPE (Standard Cast Stretch Film)

The workhorse grade — accounts for roughly 70% of global stretch film volume. Used for pallet unitization, bundling, and surface protection in non-food logistics contexts.

Produced from LLDPE blended with LDPE for improved puncture resistance and tackifiers for cling. Key performance parameters:

• Tensile strength (ASTM D882): ≥20 MPa machine direction
• Elongation at break: ≥300% (standard) to ≥500% (high-performance)
• Dart drop impact (ASTM D1709): ≥120 g/µm
• Noise on unwinding: Quiet unwind LLDPE available (important for night-shift warehouses)

Typical gauge range: 17–23 µm hand film, 12–17 µm machine film. MOQ from 500 kg.

Colored and Black UV-Stabilized Stretch Film

Black opaque stretch film contains carbon black as both UV stabilizer and opacity agent. Primary applications:

• Anti-counterfeiting / concealment: Logistics companies wrapping high-value electronics, pharmaceuticals, automotive parts
• UV protection: Outdoor pallet storage; UV stabilizer package rated for 6–12 months outdoor exposure
• Color coding: Warehouse inventory management (blue = returns, red = hazardous, green = export)

Colored film uses masterbatch additions (1–3% loading). UV-stabilized black film adds HALS (Hindered Amine Light Stabilizer) package.

Pricing: +15–25% over clear film for standard colors; +20–30% for UV-stabilized black with outdoor rating. MOQ typically 1 MT per color to justify masterbatch changeover and line cleaning.

OEM Customization: What You Can Specify

SUNWRAP offers full OEM flexibility on every stretch film order above 1 MT. Here is what is customizable without tooling cost:

Film specification (no tooling fee):

• Thickness: 8–30 micron (within standard resin formulation)
• Width: 250–750 mm (slitter adjustment, no tooling)
• Roll length: 100–3,000 m (winding parameter)
• Core ID: 25 mm / 38 mm / 50 mm / 76 mm (standard core sizes)
• Cling level: low-tack (one-sided) or standard two-sided cling
• Color: clear, black, blue, red, green, white (1 MT minimum per color)

Packaging and branding (setup fee applies):

OEM Element	Setup Cost	MOQ	Lead Time Added
Custom core label (paper, printed)	$120–200 per design	1 MT	3–5 days
Printed cardboard core	$250–400 plate fee	2 MT	5–7 days
Custom outer carton print	$150–300 plate fee	1 MT	3–5 days
Branded pallet stretch hood	$500–800 die fee	3 MT	7–10 days
Private-label inner wrap	$200–350 plate fee	1 MT	3–5 days

Total OEM example: A European distributor ordering 2 MT of 20 µm hand stretch film with custom core labels and branded outer cartons would pay approximately $300–500 in one-time setup fees. At a unit cost of ~$1.40/kg, the 2 MT order is roughly $2,800 product cost — setup is under 15% of order value and is a one-time charge.

Certifications and Compliance Documentation

When importing stretch film into regulated markets, documentation matters as much as the product itself. Here is what a well-run Chinese manufacturer should be able to provide:

For food-contact stretch film:

• FDA 21 CFR §177.1520 letter of conformance (lot-specific or annual)
• EU 10/2011 declaration of compliance (DoC) with listed substances
• SGS or Intertek total migration test report (EN 1186 method)
• Resin raw material certificates from Dow/LG Chem/Sinopec

For all grades:

• ISO 9001:2015 factory certificate (scope: LLDPE film manufacturing)
• ASTM D882 tensile strength test report (batch-level)
• ASTM D1709 dart drop impact test (batch-level)
• RoHS compliance statement (EU electronics-adjacent markets)

What to watch for: Some suppliers provide only a factory-level annual certificate. For import clearance in the EU, US, and Australia, you need lot-specific test reports or a DoC that references the specific resin batch used in your shipment. Ask for this upfront.

SUNWRAP issues a full documentation package with every commercial order — certificates, test reports, packing list, commercial invoice in the required format, and a certificate of origin (Form E for ASEAN buyers, standard CO for others).

Sourcing Checklist: Evaluating a Chinese Stretch Film Manufacturer

Before placing a trial order, verify these points:

• Factory has dedicated LLDPE stretch film extrusion lines (not a film converter buying from upstream)
• Can supply lot-specific test reports, not just annual certificates
• Has export experience to your target market (EU, US, AU, Middle East) with existing customers
• Provides a physical sample reel before order confirmation (standard 500 m sample roll)
• Can quote FOB Ningbo, CFR, and CIF to your destination port
• Has minimum 3 years of stable operation (check Alibaba trade assurance history or factory audit report)
• Responsive to technical spec questions within 24 hours — slow response pre-order signals slow response post-order

SUNWRAP has been manufacturing and exporting from Ningbo since 2003. Our customer base spans 40+ countries; our average order-to-shipment time for standard stock is 15–18 business days.
