FAQ

Problem Description: The edges and corners of the protective film start to lift or curl several hours or days after installation. The film easily shifts under foot traffic and fails to provide effective protection.
Root Causes
•Mismatched adhesive tack: Long-pile and loop carpets require higher initial tack, while low-tack film cannot form a firm bond.
•Low ambient temperature hardens the adhesive and weakens initial adhesion, a common issue on European and American construction sites in winter.
•Residual dust, sand, or cleaning detergent on the carpet surface affects adhesion performance.
•Insufficient rolling pressure traps air between the film and carpet, leading to incomplete bonding.
Solutions
•Select matched tack grades: Choose medium-high tack for long-pile and Berber loop carpets; choose medium-low tack for short-pile synthetic carpets.
•Install at a temperature above 10°C and fully roll the film to exhaust trapped air.
•Thoroughly vacuum and clean the carpet surface before application.
•Reinforce film seams and door transition areas with low-tack masking tape for high-traffic sites.
Product Tip: We offer customized adhesive tack levels for different carpet textures to fundamentally solve edge lifting and curling problems.

Root Causes: Rapid film unrolling without smooth pressing, residual fine dust on the carpet, and uneven carpet pile surfaces.
Solutions: Unroll the film slowly and smooth it evenly from the center toward the edges. Puncture and flatten large bubbles. Minor micro-bubbles are normal and will not affect protective performance.

Root Causes
•Insufficient film thickness or low-toughness PE raw materials; film aging caused by long-term UV radiation and high temperatures.
•Improper peeling method: Pulling the film sharply at a 180° angle directly causes tearing.
•The film is used beyond the maximum recommended service duration.
Solutions
•Select 80–100μm thick film for renovation and heavy-traffic sites to replace thin standard-grade film.
•Peel steadily at a 45°–90° angle with uniform force; avoid sudden sharp pulling.
•Strictly follow the rated maximum laying time and avoid overdue use.
Product Tip: Made of high-performance LLDPE raw material, our carpet film delivers excellent tensile strength and puncture resistance even at 50μm thin thickness, fully adapting to complex construction site environments.

Root Causes
•Overdue application: The adhesive ages and cross-links after exceeding the 30–45–60 day rated service life, resulting in permanent residue.
•Application on damp or incompletely dried carpets; high indoor temperatures and underfloor heating accelerate adhesive transfer.
•Incorrect tack matching: High-tack film applied on delicate short-pile synthetic carpets.
•Long-term direct sunlight and UV exposure deteriorate the adhesive layer.
Solutions
•Follow the official maximum laying time strictly and shorten the service cycle for heavy-traffic construction sites.
•Ensure the carpet is 100% dry before installation; do not apply film while underfloor heating is active.
•Conduct a small-area test on an inconspicuous spot before full-scale application.
•Clean minor residue with citrus-based adhesive remover (test first); remove heavy residue via professional steam cleaning.
Product Tip: Our premium acrylic pressure-sensitive adhesive ensures clean, residue-free removal within the valid service period. Customers can conduct long-term product verification and testing. Residue risks only rise sharply when the film is used beyond the rated time.

Answer: We do not recommend using this film on wool carpets or handmade natural fiber carpets. Natural fibers are prone to discoloration and permanent adhesive penetration. Our carpet protection film is professionally developed for nylon and polypropylene synthetic carpets, the most widely used type in European and American construction projects.
Although our products are technically compatible with wool carpets, we strongly recommend a pre-application test to select the matched tack grade and avoid difficult removal caused by excessive viscosity.

Answer: No. This carpet-specific film is formulated with targeted viscosity for rough carpet pile surfaces. Application on smooth hard floors will cause stubborn adhesive residue and surface damage. Please choose our dedicated hard-surface protection film for floor protection scenarios.

Answer: Under standard indoor conditions (room temperature, no direct sunlight), the film can be safely used for up to 45 days. For high-traffic renovation sites, we recommend removal within 20–30 days. High temperatures and direct UV exposure will significantly shorten the service life.
Our upgraded formula supports longer safe service time and allows customers to conduct comparative tests.

Storage Guidelines
Store rolls in a cool, dry and ventilated warehouse with an ideal temperature of 10–25°C. Keep away from direct sunlight and heat sources. Store rolls vertically and avoid flat compression. The original shelf life is 12 months from the production date.
Equipped withPOF shrink film moisture-proof packaging, our products effectively extend shelf life and prevent adhesive aging and residue problems caused by damp storage conditions.

Answer: For indoor temporary protection only. Outdoor UV radiation, wind and rain will rapidly degrade the PE film and adhesive, causing brittleness, cracking, peeling and stubborn residual glue. Outdoor exposure is strictly prohibited.

Mold Cause: Non-breathable film locks moisture on damp carpets and triggers mildew growth.
Answer: Our high-quality LLDPE film features micro-moisture permeability to avoid moisture accumulation. The core prerequisite is that the carpet must be completely dry before installation. Never apply film on wet or freshly cleaned damp carpets.

Selection Guide
•Short-pile office synthetic carpet: Choose high-tack grade. Short carpet piles require higher viscosity for stable fitting.
•Loop carpet, Berber carpet & long-pile engineering carpet: Choose medium-tack grade. Longer and softer carpet piles do not require high viscosity, which may lead to difficult film removal.
Always conduct an inconspicuous spot test before large-area construction. We provide free sample rolls for customer compatibility testing. Our adhesive features ultra-high versatility, fitting most mainstream carpet types without sticking or removal issues.

Answer: This is a single-use disposable protective product. After peeling off, the adhesive activity and film structural stability are completely damaged, and it cannot be reused for secondary protection.

Answer: Standard widths: 500mm / 1000mm (custom widths available). Standard thickness: 45–100μm. Contact our sales team for the latest MOQ and bulk pricing.

Answer: The film surface becomes slippery when contaminated with water, paint or oil stains. Clean up spills timely and replace soaked or damaged film sections to avoid worker slipping hazards on construction sites.

A: Problem Phenomenon: After long-term lamination or high-temperature storage, adhesive remains on the color plate/coated plate surface, which is difficult to wipe off, affecting the surface gloss and painting effect.
Root Causes:
•Mismatched viscosity: High-tack adhesive film is used on high-gloss painted metal surfaces, causing adhesive penetration into the coating layer
•Low-quality adhesive material: Recycled glue and inferior pressure-sensitive adhesive age and decompose under high temperature, resulting in residual glue sticking firmly to the panel
•Long-term outdoor sun exposure leads to UV aging of the adhesive layer and film substrate. Poor UV resistance causes material degradation and eventual glue residue on the panel surface.
•Overdue lamination: The film exceeds the effective protection cycle, and the adhesive layer undergoes irreversible aging
Solutions:
•Select low/medium-tack customized film for high-gloss color steel plates and home appliance color coated plates to ensure tight lamination and clean peeling without residue (We highly recommend that customers communicate with us or send product samples for evaluation before confirming viscosity specifications. With our rich industry experience, we can assist you in selecting the most suitable viscosity and protective film model for your application.)
•Adopt high-quality imported environmental pressure-sensitive adhesive, strictly control the glue layer thickness and uniformity, and comply with international low-residue standards. We also provide high-end adhesive options formulated with synthetic rubber and natural rubber, catering to customers with higher technical and quality requirements.
•We can adjust the production process and add UV-resistant materials according to customer requirements, enabling the protective film to meet the required outdoor anti-aging lifespan under long-term sun exposure. Therefore, full communication with customers is essential for customized film solutions.
•Peel off the film within the valid cycle; for aged residual glue, use a low-corrosive alcohol-based cleaning agent to wipe and clean

A: Problem Phenomenon: The film edges of metal sandwich panels and architectural color coated plates warp, lift, or even fall off in batches during long-distance transportation and bending processing, losing their protective effect.
Root Causes:
•The film viscosity is too low, failing to adapt to bumpy transportation and metal bending tension
•Dust, oil stains, and oxide layers on the panel surface lead to poor lamination adhesion
•Uneven lamination tension and air residue between the film and the panel
Solutions:
•Match medium-tack and strong-adhesion protective film for engineering panels and metal sandwich panels to resist transportation vibration and mechanical processing tension
•Clean the panel surface with isopropyl alcohol before lamination to ensure no dust, oil, or moisture
•Use professional laminating equipment with roller pressing to ensure flat lamination, no air bubbles, and tight edge fitting

A: Problem Phenomenon: Irregular bubbles appear on the film surface after lamination, affecting the appearance and easily causing local glue residue after long-term placement.
Root Causes:
•Manual lamination is uneven, with air trapped between the film and the panel
•Mismatched viscosity between the protective film and the panel surface, especially insufficient tack, can cause quality issues. Protective film viscosity changes with temperature: the lower the temperature, the higher the probability of bubble formation during lamination.
•The panel surface is damp or the construction environment has high humidity
•The film tensile property is poor, and local shrinkage causes air accumulation
Solutions:
•Adopt mechanical full-roll lamination with constant-pressure roller pressing to exhaust air completely
•We can analyze local climate conditions and your specific requirements, and adjust the adhesive performance to perfectly match your panels and reduce bubble-related issues. Customization is one of our greatest competitive advantages.
•Perform lamination in a dry, dust-free environment, only after the panel surface is completely dry
•For small existing bubbles, pierce tiny holes to exhaust air and flatten the film; for large-area bubbling, replace the film with a new one

A: Problem Phenomenon: When processing home appliance color coated plates and aluminum-plastic composite plates, the protective film cannot follow the metal deformation, resulting in cracking and peeling, failing to protect the bending area.
Root Cause: Ordinary protective film has low elongation and poor flexibility, which cannot adapt to the stretching and deformation of metal plates during deep processing.
Solutions:
•Customize high-elongation flexible protective film for deep-processed metal plates, with elongation up to 200%+, which can synchronously stretch with metal bending without cracking
•Avoid over-stretching the film during lamination to reserve flexible deformation space
•Select a thickened film for stamping and deep drawing processes to enhance tear resistance

A: Problem Phenomenon: After outdoor sun exposure or high-temperature workshop storage, the film softens and melts, the adhesive layer deteriorates, and the metal painted panel is prone to color difference and corrosion.
Root Cause: Ordinary films cannot resist high temperature; inferior glue layers age rapidly under high temperature, causing chemical contamination of the painted surface.
Solutions:
•Use high-temperature resistant protective film for outdoor building color plates and high-temperature processing procedures
•Control the warehouse storage temperature below 35℃, avoid long-term direct sunlight, and stack films flat without heavy pressure
•Complete the film removal once panel processing and installation are finished to avoid long-term high-temperature lamination

A: Problem Phenomenon: After a period of storage, the film rolls adhere layer by layer, and forced unfolding will tear the film and damage the adhesive layer.
Root Causes:
•Excessively high adhesive viscosity without release layer protection
•Excessive winding tension and high storage temperature
•Dull slitting blades during the cutting process cause edge adhesion, making the protective film unable to unroll smoothly for use.
Solutions:
•Add release film backing for high-tack protective films
•Control reasonable winding tension during production. Standardize warehouse storage, avoid overweight stacking, and keep the warehouse ventilated and cool
•Regularly replace slitting blades and slow down the cutting speed during processing to effectively avoid edge adhesion of the protective film.

A: Standard Operation Steps:
•Peel slowly at a 45° angle; do not pull vertically or violently, to prevent paint peeling and film breakage
•For aged and difficult-to-peel films, heat the film surface slightly with a low-temperature hot air gun (40-60℃) to soften the adhesive layer before peeling
•For large-area panels, use rolling-assisted peeling to ensure uniform force and smooth film removal

A: Answer: Qualified high-quality protective film will not corrode the panel, but inferior films will. Inferior recycled glue contains chemical impurities, which will penetrate the coating layer after long-term lamination, causing panel oxidation, discoloration and paint layer damage.
Suggestion: All our protective films use environmentally friendly pressure-sensitive adhesive, comply with international environmental standards, and feature stable chemical properties. There is no corrosion, discoloration, or residual glue after long-term lamination within the valid period.

A: Qualified protective films for metal painted panels must meet core performance indicators: moderate peeling strength, no residual glue after peeling, excellent tensile and tear resistance, anti-aging and high-temperature resistance, no bubbles or warping during use, and no chemical corrosion to the painted surface. They are fully suitable for end-to-end protection of metal panels, from factory processing and transportation to on-site installation (Tell us your specific requirements and provide panel samples, and we will conduct professional testing, customize the most suitable protective film products, and send them to you for trial evaluation. We deliver tailored protection solutions that perfectly match your panel conditions.)
