Product Details
Wholesale Multi purpose Lamination Film refers to a universal surface protection material supplied in a bulk purchase (B2B) model. It provides basic waterproof, scratch resistant, and texture enhancing functions for printed materials, packaging, and industrial components through a composite structure of "substrate+adhesive layer". Its core advantages lie in standardized specifications, controllable costs, and wide adaptability scenarios. It is a common consumable for printing factories, advertising companies, and packaging enterprises.
Core definition and "multi-purpose" characteristics
This is a roll material made of BOPP (biaxially oriented polypropylene) or PET (polyester) as the substrate, pre coated with EVA or PUR hot melt adhesive. Its "versatility" is reflected in the design logic of "one film for multiple uses":
Universality of substrate: Suitable for various substrates such as copperplate paper, matte paper, synthetic paper, cardboard, etc., without the need for frequent replacement of film types.
Process compatibility: It can be used for both hot laminating (requiring heating by a laminating machine) and cold laminating (some models with pressure-sensitive adhesive), compatible with laminating machines, laminating machines, and manual operations.
Functional balance: Achieving a balance between glossiness, wear resistance, and cost, although not top-level performance, it is sufficient to cover 80% of daily protection needs.
Typical specifications and wholesale parameters (B2B perspective)
In wholesale scenarios, the product is usually supplied in the form of Jumbo Roll, with a focus on the following parameters:
dimension | Typical wholesale specifications | remark |
|---|---|---|
width | 300mm – 1650mm | Narrow range (300-600mm) compatible with certificate cards and samples; Wide (1.2m+) suitable for posters and display boards |
thickness | 20μm – 50μm | Including the total thickness of the substrate and adhesive layer, conventional documents often use 25-32 μ m |
length | 1000m – 4000m/roll | Large coil procurement can reduce the frequency of coil replacement and unit cost |
packaging | Tray/cardboard box (usually ≥ 1 ton minimum batch) | Factory direct supply, MOQ (minimum order quantity) is usually 1 ton or whole roll |
surface effect | Gloss, Matte | Matte film accounts for about 60%, and is more popular due to its anti glare and fingerprint resistance properties |
Main application scenarios
Graphic printing and advertising: protective film covering for promotional flyers, display screens, roll up banners, and menus.
Publications and Office: Wear resistant reinforcement of book covers, folders, certificates, and archival materials.
Lightweight packaging: Surface gloss/matte treatment for cosmetic boxes, gift boxes, and electronic product outer boxes.
Temporary industrial protection: Scratch resistant layer (peelable type) for metal sheets and plastic panels during transportation.
Selection and procurement suggestions
Material selection:
BOPP film: With the highest cost-effectiveness and good flexibility, it is the absolute mainstay of document laminating, accounting for 70% of the wholesale market share.
PET film: Higher strength, firmer, suitable for menus or industrial labels that require high-frequency folding.
Adhesive layer matching:
EVA adhesive: universal, suitable for paper, low cost.
PUR adhesive: better temperature resistance (-30 ℃~120 ℃), suitable for products that require subsequent hot stamping or UV polishing.
Cost control: When purchasing wholesale, width tolerance (such as nominal 1.27m but actual only 1.25m) and adhesive layer uniformity are key factors affecting the actual loss rate. It is recommended to prioritize manufacturers with cutting capabilities.
This category is the "basic grain" of the printing and packaging industry, with the core value of reducing the cost per square meter through large-scale procurement. It is suitable for daily laminating scenarios that do not have extreme performance requirements but are cost sensitive.
